Experience is overrated. Hey, I know of an available OC who coached Heisman winning QBs, has a reputation as a QB whisperer, decades of experience, and even won a national championship as an OC. I'll give you 3 guesses at his name.
An "inexperienced" OC isn't going to accidentally call a run play when he meant to call a pass play because he is new to the booth and doesn't know how to work the microphone on his headset. What matters is whether the potential OC has a scheme that fits Miami's players. For some ungodly reason our fans are obsessed with re-treads. I feel like you guys would say, "No no, I dont want to bang the blonde hottie virgin, please give me the experienced old hag with a vagine that hangs loose like a wizard's sleeve."
Take a gamble on a new OC who wants to implement an innovative scheme.
I can guarantee one thing- it cant possibly be worse than what we have now.
