I love it how some on here are completely guessing what has been said and what has happened during an altercation where they couldn't hear anything, and then justifying their guess with plays that have happened in the game earlier.
There's every chance that Morris could be yelling at Goodwin for something to do with his play and trying to be a leader. However there is also every chance that Morris is doing this in a completely incorrect fashion for a leader and ended up going too far.
What it does seem like from the outside is the Morris twins seem like a completely toxic presence to any locker room unless they're "bestezt frendz foreva always togeva sharing contractz n thingz". However, just a guess.
