I think that is likely to some extent but at that same time we don't have the playcalling depth Meyer used at Florida for the H-back position. With Harvin there were fake sweep dives(with the HB carrying the ball), HB/RB/QB triples options, HB/QB/TE triple options with fake jet sweeps, Fake jet sweep screens, etc. I suspect a big part of the reason we haven't had the same variety is that we've had the type of dominant workhorse RBs Florida never had(and no one who blossomed like Harvin at HB). Hyde and especially Elliot were some of the top producers at RB in all of college football.
Also keep in mind that despite all that has been said on the H-backs they have still been very productive...just not as much so as the HBs at UF. Dontre Wilson in 2013, Braxton Miller last season, and Curtis Samuel last season have all been productive from the position. All approached or surpassed 6 ypc and put up a decent amount of receiving yards.
