Your logic here proves our point about Deangelo Williams. Williams is 28...but has never been a true feature back. He has always split carries with another back. Williams is never abused in a game. He has many good years left in him. There is no point in being critical about our GM, who rewarded a top tier RB (who's career average is well over 4.0 ypc) that has been underpaid his entire career. Good players with high morale play much better than one with low morale.
You're comparing apples to oranges here.
I'm making the case that Turner has a few (1 or 2) years left because of his time spent backing up LT.
You're making the case that DWill deserves a 5 year, 43 million dollar contract because he has split time the last couple of years.
Not seeing it.
Cause it just isn't there.
