My mistake. Though you were talking 1:3 PA:IS (i.e. 5 PA: 15 IS)
And yeah, I realized that too somewhere between S11-S13 and made PG and SG with IS for myself, too bad so long ago we don't have a clue about the extreme changed on salary that BB were planing (reduced salary to half and even more).
(14591986) and
(11977302) arrived my team with 18 yo and 19 yo. Both were well trained and have an outstaning IS, but also the others Inside Skills.
And again, a 2-3 zone were C have a high SB (let's say 14-16) and PF & SF with decent values (7-12) could stop that kind of guards easily even with the old G.E. But hey, they don't need to have a extreme salary if you give them HA,DR (free and don't have to train in diferent position) PA (free) and JS. Most Inside player don't have OD and M2M D it's the most popular D between managers.
