From what I understand this disagreement with Lee and Jackson could be similar to the one we saw a few years back with Barret Jones and AJ Mc.
From what I have "heard" the argument was over the shut out. One of the guys was saying, so what if MSU scores, while the other was still wanting to bust ass and preserve the shut-out. Hence the pushing and shoving disagreement.
I don't think this is something that CNS is going to punish, if this is indeed the case. You have players that are balls deep into the process and spats like this prove that.
