Nothing wrong with a mother wanting her son to act respectably, nor is it admirable for players to act inappropriately. Nevertheless, pro football players are anything but choir boys and that's, unfortunately, a common characteristic that pretty much goes with the territory. Maybe Lawrence might see fit to change his rough edges but I wouldn't necessarily count on it. Some of us find a way to adjust our actions, some don't.
More often than not, leopards don't change their spots, although, we'll soon see what's yet to come in this particular instance. As long as he continues being a capable player, I'll be satisfied. For me, his conduct is a personal matter to be dealt with himself. No doubt but what he'll take his lumps if those "rough edges" continue. The onset of maturity occasionally inspires change. Good luck to him with that.
