Geno's run was against some form of the Psycho I think. Peppers was the only lineman I saw, but it might have been a 2 man line.
The 4-3 is also having WAY too much trouble with misdirection. Part of that is Matthews who commits before he has a read and you can't do this as the second line of defense esp. when you have contain.
They are still working out the kinks.
