Sure, I agree with you that TH was better (and still is). With TH as the QB, we would be 10-1 now, with a fairly respectable loss at Michigan (i.e. not a blowout) our only blemish.
I would love to see TH back next year, even with the issues this might bring with how to best handle TH/TM. But I also don't worry about TM's development. He's the best we have ever seen at this stage is his career, so I am very optimistic on where this is going.
