BJGE, then Woodhead, then Welker.
I never figured BJGE would make the roster, and then he rushed for 1000.
Woodhead because I saw him as a 'scouting' acquisition with his size, and he turned out to be a played. I thought the loss of Faulk would hurt in a huge way, but Woodhead was a more than capable substitute.
Welker because I figured he would appear mid-season, and then he would have lost some of his quickness. As he relies on quickness and cuts, I thought he might be done for good after his injury.
