sorry but this is the problem with your offense. it's too cute, too wild. Your offense has no true identity, one play it wants to be a physical domimant team, the next it wants to be up tempo spread out option, the next its a spread wildcat formation. There is just too much goingo on.
Every time Martinez carries the ball, I expect him to fumble.
Coker and McNutt are Iowa's whole offense. Stop at least one of them and you're gonna be fine.
the one play i really like by nebraska and it seems to work all the time if martinez can throw it correctly is the Belly G Option Play Action pass, or whatever it is. If Oregon ran this I think it be a money play. but Nebraska runs it maybe 2-3 times a game and it seems to either always have a chance but is messed up on the throw or if they do connect itst a big play, they should use this play more often.
What that will do is the defense will have to worry about the pass off that option play so you wont get the safeties up to stop the run, therefore you open up the run play off that belly g option PA. run it a few more times, defense commits to the run then BAM Play Action throw it deep.
