If, in fact, the main problem is lack of player execution... which is quite reasonable... then let us ask why the players are not executing. Here are potentials reasons for lack of execution.
1. players not knowing well what their assignments are --- this comes back to coaching... make it simple enough to comprehend and execute
2. players do not line up correctly on defense (which happens a great deal) --- this again comes back to coaching... make it clear where they should line up
3. players are stressed and unsure, in part from reasons #1 and #2 --- and fear being publicly ridiculed by coaches if they fail to execute... so they play nervous and unfocused
4. the players simply are not D1-level players --- they know what they are to do, but do not have the skills to do it.
There are likely other reasons for lack of execution as well. But... generally, most of the reasons come back in some way to coaching. Adapt the scheme, the communication and the assignments to make them doable given your talent --- and provide a context whereby players can play hard w/o fear of being wailed upon if the do not execute what they do not understand.
That is, largely the lack of execution of this magnitude across so many players to this degree... well it comes down to coaching again.
