Fighting as Greg:  His boxing game is pretty straightforward.  The best part of his ability is the +1 damage to Jab, leading you to a head-focused standing game, and one that can stop the shoot ins.

Fighting against O’Connor: If you’ve got any ground game at all, you’re going to want to take him there, but you’ve got to get past his Jab.  To do that, you’ll have to deliver some heavy blows and get him Blocking, opening up chances for the Shoot.
