its less about his value than having a cohesive big board. the big board setup is a handful of linear formulas - its not going to be perfect in edge cases. this guy SHOULD be an edge case, IMO - its just that the current PG / SG formulas are so heavily per driven, and so lp-agnostic, that there's a clear balance issue. the most premium guards are per scorers, and the rankings should reflect that - a guy like yours, or the one i just had barely drafted 58th / 105ish big board despite being slightly better outside stamina, should always be a bit of a discount (your guy is probably better w/ stamina)

anyway, i think these guys can be real good, but its definitely harder from a team planning standpoint to incorporate such players into a championship level rotation, than the elite guards with per scoring. i would be fine if your guy was a high end 2nd round guy even, or mine, but they should be automatic selections as seniors, i feel like having guys like these missing the draft and barely making it, its too far.
