I think you got an ok deal. There are a lot of players on the transfer list this week b/c of the draft. But just to play devil's advocate, this player is short for a center so his inside skills won't accelerate with training as well as a seven footer. Also, his secondary skills are really terrible. Doesn't block shots (not sure how important this is in this game), doesn't pass at all (which is important for game flow and having your center pass is very helpful) and his jump shot is atrocious which means he can't play any other position except C.
He can be useful in a Division V league, but I think many people wouldn't go to the trouble to train this type of player.
