Patrick Mahomes preseason game three: something improved and something that needs improvement This is part three of a three-part weekly film analysis on the performance of Patrick Mahomes.Part one here Damien Williams Jersey , part two here.There is noticeable improvement and reason to be optimistic every time we see Patrick Mahomes take the field. He’s both wowed us and given us hope for his ascension to the franchise quarterback this city has desperately craved. Sometimes, I forget how difficult a transition he is making from his time at Texas Tech to now. He was very raw, very green coming out and it still shows. From last week’s game, we have talking points about the same facet of the game, but on opposite ends of the spectrum. There are areas of improvement and areas that require improvement in Mahomes’ work from the pocket.Something improvedWe need to see this happen more often (more on that in a minute), but Mahomes is becoming more space efficient when he hangs in the pocket.Mahomes is gradually learning to work within tighter spaces. Where we’ve seen him literally run to space in college to work in a uniquely large and wide pocket and still fight that urge in the NFL, the clip above was a very encouraging sign. The potential for Mahomes to be lethal from the pocket is tremendous. He doesn’t need a ton of space to set up because of his arm talent and fearlessness to pull the trigger, so he has the potential to create big plays opportunities other quarterbacks can’t. Tom Brady is phenomenally efficient with his movement in the pocket. Everything is subtle, quick and he finds the best space he has to work with great consistency. In college, Mahomes’ pocket was large, wide and oddly structured, and it led to bad habits. It’s not remotely as big in the NFL, and the players coming to get him are bigger, faster and stronger. Efficiency of space is everything. The old saying, “aim small Tyrann Mathieu Jersey , miss small,” works here. He’s never needed to aim small. He could literally run up in his pockets in college. He can’t get with the extra half-step here or there now.His movements are starting to tighten up. He’s starting to aim small when he’s working within the pocket to find the best space. It’s just a matter of him getting enough live reps to understand when to leave, when to hang in the pocket, when step up, when to back out. Speaking of which...Something that needs improvementIf only we can get him to stay in the pocket long enough to continue to develop his management of tight spaces. The decision making from play to play has been inconsistent. He hasn’t consistently made the right choice about when to hang in and give the design of the play a chance, when to ad lib or when to run for yards. It’s wildly inconsistent. In the clip above, he leaves a clean pocket too quickly, hangs in too long with an open receiver in front of his face and finally elects to run for a touchdown from a clean pocket.There doesn’t appear to be a consistent logic to it yet. Brady, for instance, on that last clip, would stay in the pocket to see if he can find someone on the back line of the end zone for as long as he can, only using his legs as a last resort. Mahomes saw the routes covered and decided to make a break for it immediately, even though he could’ve given his playmakers time to separate. He’s too early and too late in different instances. These clips appear to be the times that Mahomes is thinking the most on the field.All those clips were from the third quarter. He may have been feeling the pressure he’d faced all day. It could’ve been affecting him. That’ll be something to look for moving forward. There’s both good and bad happening in his navigation of the pocket. It’s just a matter of putting all the pieces together. It’ll take time, but there’s promise amidst the issues he’s dealing with. He can be exceptional from the pocket someday, but he’s got to smooth out the rough edges of his game in that regard. KANSAS CITY Steven Nelson Jersey , Mo. — Emmitt Thomas announced his retirement Tuesday as the defensive backs coach of the Kansas City Chiefs, ending an NFL career that began as a Hall of Fame player and wound up spanning five decades.Thomas spent 13 seasons playing for the Chiefs, helping the organization to a pair of Super Bowl appearances and their only championship in 1970. The two-time All-Pro retired in 1978 and began coaching at Central Missouri State before moving onto the pros with the St. Louis Cardinals.He helped the Redskins win a pair of Super Bowls, and also worked for the Eagles, Packers, Vikings and Falcons, before returning to Kansas City in 2010. He’s been the Chiefs’ secondary coach ever since, first under Todd Haley and retained by Romeo Crennel and current coach Andy Reid.“My journey started in Kansas City, and by the grace of God I am able to end my NFL career here as well,” said Thomas, who was enshrined in the Pro Football Hall of Fame in 2008. “It has been a privilege to work alongside the great coaches that have come through this building. Having the opportunity to coach so many talented young men in my time as a coach has been one of my greatest gifts.”Thomas joined the Chiefs as an undrafted free agent out of tiny Bishop College in 1966, just four years after the organization moved from Dallas to Kansas City. He helped the Chiefs reach the first Super Bowl as a rookie, losing to the Green Bay, before returning three years later.He had nine interceptions that season, including one in their Super Bowl triumph over Minnesota.Thomas continued to be a productive player until his retirement Tony Gonzalez Jersey , then became a sought-after coach for defensive backs. He spent four years with the Cardinals, eight more with the Redskins and three with the Eagles before serving as defensive coordinator of the Packers.After a stint as defensive coordinator of the Vikings, he joined the Falcons coaching staff, where he got his only taste as a head coach. It was Thomas who was appointed interim coach after Bobby Petrino’s sudden retirement in 2007, and he rallied a broken locker room to a season-ending win over Seattle.He was retained by new Falcons coach Mike Smith the following year, then joined the Chiefs in 2010, a move that allowed him to bookend a playing and coaching career spanning 51 years.100<button class="view-gallery">View Gallery</button> Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta“Over the course of a career that spans two leagues and most of the modern era of the NFL, Emmitt was a Hall of Fame player and one of the most respected coaches in the league,” Chiefs owner Clark Hunt said. “Emmitt will always be a part of our Chiefs family.”The 75-year-old Thomas’ retirement had been expected after the Chiefs, who lost in overtime to the Patriots in the AFC championship game, fired longtime defensive coordinator Bob Sutton.Steve Spagnuolo has been hired to handle the defense and is bringing in many of his own assistants.“It was an honor to have Emmitt on our coaching staff,” Reid said. “Having a Pro Football Hall of Famer lead that room and share his experiences as a player and a coach has been incredible for our guys. Beyond football, he’s a tremendous person, and I’ve enjoyed working with him and getting to know him.”
