I don't think Riley/cav will be able to keep some of the 2nd stringers out of a game the whole time. They will have to rotate Wilson and Farniok and maybe one other in from time to time.
As stated by Blitz this is so over-discussed. There are great O-line teams that have rotated individual players and great O-line teams that have rotated by groups. NU just need to become closer to great again - how ever is up to the staff.
