Actually, IQ won't increase any faster if you play it than if you don't play it. It doesn't make any sense that this is the case, but it indeed is the case.
Also, fwiw, your Wooden UNCP team will then be FB/FCP, but I really think you need to sell out more for ATH and SP during recruiting to make this work properly for you and make that next step up with that team. 53/46 really isn't good enough at D2. In fact, it's barely good enough to be running just FCP (with Motion) much less the FB/FCP combo, imo.
