I think a lot of people forgot or are unaware he had the
2nd most receptions in the history of the program for a sophomore (48), and that was after he was immediately after he was switched from RB to WR.
GM did a remarkable job botching what should have been a good offensive unit last season by making a variety of awful moves but the way he tried to use Ashton was perhaps his biggest shortcoming. I think he was moved to a different position 3 times in one season. Not great for a guy who is probably not well suited to learning responsibilities for several positions, especially not while hurt or playing hurt most of the year.
The way GM used the H-back position, where the receiver get the ball in tight coverage over the middle most of the time, is not the right way to use Broyld. It puts a premium on toughness and ability to catch the ball in traffic.
For a player who is not a natural receiver and doesn't have a lot of experience catching the ball, it is crazy to put him in that position. He is best when you get him the ball in relatively open areas, where his ability to make people miss and run to open space is put to best use. Get him in situations where he needs to beat one man to get a good gain and he will be successful. A lot.
Anyway, I think if Ashton is used in ways that emphasize his strengths and help to hide his weaknesses, he will be successful.
