Yeah, GT or any team that runs the flexbone/wishbone (Army, Navy, Air Force).
Also, you should check out ND. They have two great speed backs (Atkinson, Carlisle) a good true freshman HB that can be turned into a fullback (Bryant) and a couple mobile QBs. With them, I was almost entirely running flexbone/wishbone as well as a mini-scheme out of shotgun spread involving putting both runningbacks at slot and running a lot of jet sweeps, jet options, and fake jet dives with Bryant in the backfield.
FSU also has a superb roster for your type of offense. With them, I ran almost entirely out of pistol, using a lot of crowded backfield formations. They have three very good runningbacks from Freeman (balanced/speed) to Wilder (balanced/power) to Pender (speed). Wilder can play that FB roll much like ND's Bryant, but with the pistol that wasn't necessary, but rather I simply used formation subs. If you're looking to run exclusively the diamond, either teams work, but I think FSU has the edge with runningbacks better suited to pound the ball and a QB who can be very dangerous downfield. Also, Kelvin Benjamin is that monster downfield threat that you wanted measuring 6'5 and 243 lbs. Compared to real life, he's modestly rated, but his 85 spc 81 cit and 93 rte combined with his height and 97 jumping make him deadly, especially in his Junior and Senior seasons.
Personally, I'm looking for a team that can run these types of offenses, but much more lowly rated and in a less competitive conference as a rebuilding challenge but I've yet to find a good fit. If anybody knows of a team with 2-3 good HBs (compared to their relative competitions) and a mildly fast QB let me know. The closest I've been able to find is Kent State but their QB's speed doesn't quite cut it.
