Tim's mobility is a huge plus at the QB position. What he needs to improve on is his reads, when running the zone read, inverted veer, etc. He simply guesses far too often, rather than actually allowing the play to develop and making the proper read. He had the same issue at UF ... but that offense was just so talented that it didn't matter.
His future isn't with NE, but it's at least possible (even if the possibility is remote) that McDaniels would give him a shot when he gets his next head coaching gig, whenever that may be. By that time Dan Mullen should be out of a job ... maybe you just go for it, bring Mullen on, and go all in the with the Meyer/Mullen spread.
