Trent has the right frame for the weight though. Abdullah on the other hand doesn't. Some people just can't put on 20 pounds without it being fat.
I'm no nutritionist or athletic expert, but is an extra 15 pounds of muscle really that unreachable for Abdullah? I'm not saying he needs to be 230 pounds, but is 200-205 pounds implausible for him?
If he is already physically fit, minimal fat, which I think is his case, its much harder than you would think. Possible yes, but not as easy as hitting the gym and getting a good work out. It takes a lot of dietary, intense and long workouts, and doing it with no performance enhancers makes it much more difficult.
He may have already gone this route and found out that he isn't as fast or elusive too. Take that as a grain of salt, as its just my opinion, but if it was that easy, and he got faster, or stayed just as fast/elusive, you think it would be done already. They have formed Cross into what they want, and are continuing to do so. You'd think they have already done that with AA.
