He is a good trainee.
If he were to be given a BB rating it would be like, Prolific. So its not like he is the best trainee int he world ever, but he is certainly very far from a useless trainee.

In terms of salary cap, generally you are looking at over $100k. But it depends on skill level. In buzzerbeater it was previously commonly thought that Potential determined how high a players salary could go. However this has been proven to be slightly incorrect and salary capping is now based on combination of potential and number of skills, in a ratio formula based relationship.
