Way to misrepresent a position. Yes, a difference of less than 3" in height is practically irrelevant when it comes to the ability to see downfield. If you don't know that QB's throw through passing windows and not over linemen, then you quite frankly don't know anything about football.
As to your second point, I never stated rhythm didn't matter. My entire point was that its an absurd overstatement to act as if Harris being inserted into the game for all of 10 plays in the first half somehow led to Grier making poor decisions in the second half (when Grier started the second half) because of 'lack of rhythm.' Grier played almost the entire game leading up to the 4th in the last game. And if that's your argument wouldn't that also apply to Harris? Or does only Grier's rhythm get disrupted by the rotation? Clearly you're just interested in making excuses for one side of the QB equation. But hey according to you Mac cares more about his QB rotation than winning, your words. That's great wisdom on display by you. I think I'll stand by my takes, thanks.
