WRs come in and out of games consistently to keep fresh, unlike the OL. Whether he starts or not, he will play in every game unless he is injured. If any WR red-shirts, it won't be him unless he gets injured.
Will there be a learning curve? Probably. But that doesn't mean that he won't play. Look how quickly Stanley Morgan played his true freshman year (albeit partially out of necessity due to injuries). They will have him in on plays that he knows and excels at and if he is open, POB or TLee will get the ball to him.
We will have 3 or 4 WRs on the field every play and probably 11 WRs seeing the majority of the snaps (8 scholarship and 3 walk-ons).
If we are winning in the 4th quarter by a comfortable margin (hey, it could happen!), you can bet the backup WRs will be getting some of the snaps.
I just hope that with 18 WRs on the roster this year, that they won't overdo it anymore in Fall Camp and pull so many hamstrings.
