Hey man,
He'll already be in the good books for the NT at the moment with those skills at 20! :D I'd imagine he'll be in the consideration for U21 NT now.
Seems to me the problem is that NTs want the skills that raise the salary to horrible levels! i.e PS for a PG, or JR for a SG. Personally, I would aim for 20 OD, and 14 PS minimum. That gives more flexibility on the NT tactic used. I mean, you know the rest, but secondaries are required only to the specific NT manager's preference - some love RB for all players, others value IS for PGs, and ID for everyone. Get a feel with Rambo what he likes, he might well be the NT manager in 2 seasons...
