So I think he will be at least 3rd the best guard in Your squad (if You set him as PG/SG), maybe even 2nd. You tried to buy 2 in 1 so it's obvious price was higher than typical ;-)
And my opinion is that this player is too good for III div. You don't need primaries = 14 for big men, and You don't need JS better than RB, so this player wasn't adeqate for Your team. You should buy big man with primaries = 12-13 (sum of inside skills = 40-45 and sum of outside skills = 35-40 and every skill at least >=4-5). It's possible to buy similar players under 1M and it's enough multiskilled player. I have 3 similar players and every costed less than 1M (550k, 600k, 900k).
i agree with you but as I wrote above, this does not really change the case. Maybe in league III it is more meaningful to talk about JS 6/7. But then you shoould probably defend also with 5/6. Add passing & handling 4/5 and yoour player is much more expensive. And again: even thrash centers want more salary than decent guards.
