Postma MUST be the starter. He has worked in this system for years. He has performed under pressure (Memphis), and can run the ball. With Allen there is no read option. It is just everyone converge on the RB. It gives the D one extra man against this O. If it were Air Raid, then fine, Allen is your man...but it's not.
Postma made it look sooooooo easy. Allen made it look so hard.
Add in KA continues to be a turnover machine another 2 Ints and a fumble) and you know a change needs to be made.
We had 233 yards of O going into the 4th. Postma almost equal led that.
Lastly, TT has a horrible D. Even the TT fans around said it. But our Allen run O made them look super. When Postma came in they thought, "Ohhhhh, sheeeeeet"!
Give The right QB the chance to play.
