Young is not built to play the role that Reeder does. Reeder is a part time starter - he plays heavy snaps against run heavy teams. He's terrible in coverage, but he is very good against the run. Also good at special teams. Reeder will be here a long time doing dirty work.
And why are so many still writing off Hill - you know, the guy they signed to a 2 year contract extension. The guy only allowing 45% of passes thrown his way to be completed. That guy, who's 6.0 YPT given up is top 10 in the league. That guy, giving up a passer rating of 64 against. What's it going to take for Hill to get respect?
