Cassel is not mobile and he has been known to hold onto the ball too long. His sack issues are far from all the Chiefs’ offensive line’s fault. Cassel was sacked 47 times in 2008 as Tom Brady’s injury replacement in New England. In 2009, Brady was sacked just 16 times.
In fact, Cassel has been the second most sacked quarterback in the NFL the past two seasons, his only seasons as a starter.
