The Carey move inside is good but Columbo possibly starting at RT is awful and far outweighs the move of Carey. You plugged one hole and left a gapping hole somewhere else and this seems like an indication Jerry isn't getting the job done.
So let's see how the great O-line coach is doing with his picks:
2008 Draft
1st Round - Jake Long - stud, franchise LT
4th Round - Shawn Murphy - sucked and cut
6th Round - Donald Thomas - lasted 1 and a half seasons and cut
2009 Draft
6th Round - Andrew Gardner - hasn't done jack CUT IN 2010
2010 Draft
3rd Round - John Jerry - looks to be on his way to the bench, possibly cut
1 out of 5 players drafted...not good. We have better luck with undrafted free agents on the O-line.
