dude your team got stacked. You have three decent big men that you can train (Especially Serrano and Patton). They are all 18 years old, but unfortunately they will age in about a week haha, but they are still all very good to have. I would look at improving your trainer and getting advice on how to train those guys. You got very lucky with your team ;)
