Deaderick, 6'4 and 305 pounds, went to Alabama playing on a defensive line that won a national championship in 2009 (even though he was shot). He was a seventh round pick by the New England Patriots in 2010 and actually saw some playing time with 14 starts over his first three seasons in New England. The Patriots cut him prior to the 2013 season and the Jacksonville Jaguars claimed him off waivers where he logged one start, nine tackles and one forced fumble. He played against the Chiefs last offseason and had one tackle (seen in the picture above).
The Chiefs theme this offseason on the defensive line seems to be about creating more pass rusher. Free agent signee Vance Walker is a good example of that. Deaderick is not a great example of that as he is more of a run-stuffer than a pass rusher at defensive tackle.
The Chiefs will try players like him out throughout the offseason and even during the season. They need the names and numbers of free agents in which they have some interest in the event an injury comes up.
Speaking of tryout players, one of them recently had some success in Kansas City when Ryan McKee was inked to a contract after trying out for the Chiefs at their rookie minicamp.
