Personally, I love Monty with our FA TE signings. The Pack can come out in 12 personnel. What does the D do? Do they play heavy run, base or nickel?
If the D plays run heavy or base you can split Monty and/or 1 TE out. If they go nickel, you pound the ball into a 6 man box with 7 blockers.
Effectively 12 personnel for the Pack is a hybrid 02 with a WR playing RB. It can be a heavy run package or similar to a 5 wide package.
