The bolded part above is THE issue.
If teams are going to bring multiple blitzers a majority of the time, that means our TEs and WRs are in single coverage.... and yet they still can't get any separation at all..... why?
And OSU seemed to mostly bring the blitz right up the middle.... so in that case you should be able to beat them by going to the edges horizontally.... but we rarely seem to exploit that. And if they are bringing the heat right up the middle, then you need to roll Purdy out on designed roll out plays (which I assume Manning doesn't have??).
The best QBs in college and the NFL absolutely LOVE when teams blitz them. Aaron Rodgers comes to mind for me. He's said over and over again that he loves being blitzed.... because you can burn blitzes for big plays.... or you should be able to anyway. Not us though.... we have no idea what to do??
The receivers don't get separation because they're not fast.
