Check with me O works on occasion when you want to catch the D in a certain set and expose the holes, but if you do it every play, they will just learn to disguise in base until after the QB "checks with coach". The time also allows the D to rest, knowing they have time yet to relax for the check, makes the OLine sit in their stance forever, and kills rhythmn.
With good coaching, the QB can and should make those reads and check at the line when he sees something juicy. The offense shoudn't be so complex that he can't at this level.
