The IlB just need to run sideline to sideline to be effective. With the Jennings\Lewis sandwich, offenses will have to double team one of them while running from the other. They'll run right into the Bama ILBs.
If it was not an internal thing, the only thing I saw that could warrant discipline was when he sort of walked off the sideline talking smack to a Mizzou player that was a little rough pushing a Bama player out of bounds. TV caught him talking aggressively towards the Mizzou player at the end of the play. Not a very "leadership" thing to do, and Saban seems the type that would call someone out on that behavior.
