LOL, give him a couple games and he will be level 2, then you can put some more points in different things.
I always recommend you use your daily training to put directly into stamina.
Stamina is the driving force that determines how many plays you get per game. The more plays you get during the game, the more experience you gain from said game.
Place your skill points into something that directly affects the position you play, i.e. catching for receivers, speed for generally everyone, str for lineman on both sides, etc.
