You can coach running backs, or any player for that matter, however if they do not adapt to the coaching as well as others or do not take to the playbook and blocking schemes of the particular offense quick enough, how do you just blame coaching on their lack of growth. Kevis Streeter and Aaron Spikes are in town working out with the team and while they have likely started learning and studying the playbook, nothing makes up for repetition in live drills and action to absorb the information as second nature. These guys will have literally one month to do that. By the same account, Tyrell Fenroy came in and took to it quickly and started and flourished from his first moment on campus. I'd venture to guess that they "coached" him similarly to how they will prepare these young men. For these running backs now, preparation must meet opportunity and I feel strongly that they will do what they have to do to grasp the offense and present their best case for playing time. I do not think that you will see one back emerge however, but do not confuse a committee approach with lack of coaching or lack of talent.
We adapted this offense some years ago to meet the talents we had on offense which were versatile quarterbacks who could run and throw. I think that the QB's we have now are very similar to that of Jerry Babb who flourished his first two years in this offense. Desormeaux was a bit different as he was a much better runner but obviously not as talented passer. However, he had smarts, character, leadership and toughness to go with his athletic ability. I think that is why we went away from the triple option sets we saw often with Babb to running the single option zone read offense we now employ. I would much rather go back with the triple option sets using two of our talented backs in the backfield at one time while still allowing the QB to set up the run and take it when need be. None of our QB's should run the ball much more than about 10 times per game max but to say that we shouldn't utilize their mobility is not rational. These QB's are mobile and that is an asset not a liability. It proposes another variable in an offense that is geared to take advantage of spatial matchups and advantages. I'm not sure how or why you can say that having a running QB is a failure for an offense but that ideology is proved wrong in every conference in college football.
I'd say that Masson played pretty darned well last year given his inexperience and lack of options in both the running and passing games. He is given many more options this year with the athleticism we have at RB and the returning experience in the receiving corp.
