Every time I see that I cringe, something that is too obvious. You have the offensive line lining up straight across, then the QB comes over center. Then the backs line up even with the QB and everyone plows forward. All for one yard at the very maximum or even a loss.
The main problem with this play is when the backs line up even with the QB he has no chance of sliding left or right because he is being blocked by his own players.
I find it is very easy for the defense to read, as they see the backs coming forward, and such an awful designed play could result in turn over on downs or lost scoring attempt.
