Hey, nice to meet you. If you have any questions about the game, feel free to shoot me a BB-Mail. I've actually played awhile before, so don't let the DV fool you, I went inactive before and only recently returned to the game.
From a glance at your roster, you have a great starting team! First of all, I would cut it down to 12 players, because that's all you really need. The ones you cut are really just scrubs, so go ahead and fire them, they won't sell. Agee, Harman, Whitlock and Ojeda look really good and would be excellent starters. You've also got 2 great trainees in Cooley, but especially in Hawthorne, who I would focus on as he has the most potential.
I would put what you can into the draft, being a new team you can get some good players to build up your team with, or someone who can sell and get you a few quick bucks. Speaking of which, I would invest most of your money into expanding your arena, you're gonna need it when you start winning. :-)
Finally, I would encourage you to sign up at the offsite:
