Well, since this has gone on beyond what I wished, I suppose I should reprise a post I did some months ago (you can check) about the entire situation.
Remember the "Snoddy is our next great BB" experiment? When we - or, to be more exact, the coaches - wasted almost 2 years trying to make Snoddy into a BB? It was for the same reasons folks have been bringing up here: big enough for the position, no real juke to him, fast as lightening, "we'll run the speed option again!", ect., ect, ect.
I don't have anything at all against Marshall. He is just like Snoddy: he's big enough to shed a block, he has great straight-ahead speed, and he's tough. And, I think, just like Snoddy, if he was out at AB, he could be another Orwin Smith. MLD will go back to BB this spring and we are loaded there. But with Snoody gone we no longer have that AB who is big enough (over 200) to take on an OLB and strong enough to shake off a downfield hit, and fast enough to take advantage of it. That is why I want Marshall out there. With him at AB our first 4 on the field will all be 190 or bigger and cut 4.5 forties or below. You know, sorta like 2014 (Perkins and Hill). The problems that would cause opposing Ds are unsolvable. With him and either Lynch or Green (probably) out there starting, I think both starting ABs could average 9 ypc or better.
Out at AB - where we could use him at once - he would probably start with Green. At BB - where we are absolutely loaded with candidates - he might or might not see the field. I want him out there where he can do us - and himself - the most good. That's why I keep saying he should move. We've got plenty of good BBs; I think after this spring Coach will decide not to waste another season or two trying to keep him there. And that has absolutely nothing to say about his frosh AA honors; I believe I've said enough about that already.
But, again, I will not say another word about this if he turns out to co-start at BB. That's Coach's decision. (I know, I know: I keep promising and can't shut up. This time for sure. Provided, that is, that I don't see any more really strong bait.)
