DeBoer's offense don't hand the ball off much as far as I can tell, plenty of games where the quarterback kept the ball 75% of the time and if you check that happened this season as well (12 hand offs in the Michigan game for example). So, this seems to be as much a feature of his offense he learned from DeBoer as much as anything else.
This is one reason I kind of hope that they bring in an outside person (and why I threw a bit of a fit when another buddy was hired before any offensive staff was replaced) who can establish a balanced offense. Having said that though, Grubb is his guy, if we want to see what a DeBoer offense is supposed to look like then that's who should be the offensive coordinator. So I'm alright with Grubb, just not a huge fan of Sheridan who was brought in to be the tight ends coach but is also a DeBoer disciple, as he is just the less accomplished of the two.
