It is about using the skills you have. Byron scores by uses his speed not being playing big.
Gallagher is one of the extremely rare players that plays big to create offense.
If Byron tried to play the way Gallagher does (aka plays the big game) he would be pretty much useless because that is not his skill set.
Byron plays in traffic and goes in hard to play areas to score, it's a big part of his success.
Speed is a big part of his game but he is a player who plays with very little fear, he's a lot closer to Gallagher than you think.
Case in point last night he had no fear going into the corner first even if he knew there was a 6'6 monster right behind him, and what happened, he took a very dirty hit.
Anyways, my point is that you can't get away with cheating if you're small and don't have a great skill set....speed alone isn't enough.
Unfortunately bigger players always get away with cheating because everyone sees potential in players with size.
