If Williams is a 1 and done, I wouldn't mind taking 6WR's in this class (Williams, Upchurch, Noil, Dupre, Quinn, and Blacknall). It probably won't happen though. I can see 5 at a max in this class.
I think this depends on who steps up this year. If it's Leslie and Landry or OBJ, we may take 6. If it's Wright or Boone, 5 would probably be it.
If it's Dural and Peterson, 5 would be more likely than 6. But 6 would not be out of the question. Both are more eligible to leave for the NFL after the '14 season.
Personally, I'd like 5, with or without Williams. I just prefer to not load our classes up with ridiculous numbers at one position. Spread it out over a few classes.
