roughly, i would say we know for a fact that speed has no bearing on the rebounding ability of bigs. defensively, it sure seems about as useless as <insert metaphor>. 'guard skills' or ball skills or whatever, bh/pass primarily (turnover prevention and getting team mates better open looks), both seem pretty minimally useful for bigs to start with and we know the latter values speed 0 even for guards, so i'm not really buying there is anything more than negligible speed value there. offense is the only area i see value.
this means there is roughly a dichotomy - reb/def type bigs, which is basically the only worthwhile big types that existed in my formative years (when bigs were significantly worse on offense than today), in which case i would completely ignore it (think durability). its significantly worse than 1/10th as valuable as ath or reb for those players, in my book. for reb/def type bigs - which should be a major archetype in the view of basically all coaches - really its only ath, reb, def, blk, and sta that are worth considering. i'll take a 95 ath/reb/def/blk/sta big with 1 in everything else (ok maybe not WE but i'm talking game ratings only) and be thrilled - at the highest levels of championship play in d1.
on the other side, you have scoring bigs - and of course, there's a gradient in between (a 7ppg big, for example). there, i see some speed value. in general, i don't consider lp to be on the ath or reb level even for scoring bigs, but if i really need a scoring big, lp starts to get up there - it gets close-ish, i suppose, maybe 80% as important for a pretty strong scorer, or something? the thing is, even a 95 ath/lp guy is going to be solid - but not great - you really need like 50 spd and 50 per and c+/b- ft to go along with it, to have an 'elite' scoring big for high d1, and that is *so* much harder to find than a reb/def type. you need all that lp and per and speed, thats like 200 points of stuff just for offense. its hard to ascribe too high a value to (lp, per, spd) because you need so much for it to really be worth anything and a huge amount for it to be worth a great deal. a mediocre big scorer is worse than a mediocre guard scorer, there's really not much point to them, bigs are still the inferior scoring players even though its by less than the old days.
if you value ath/reb around 1 point per, i would think an offensive big could merit, on the high end, .3 to .4 value on speed, because its no where near lp importance and lp is like what, 0.8, maybe up to 1.0 range if you are really, really desperate for offense - not only big man offense, but as a team? perhaps down in the 0.5 to 0.7 for a scoring but not top tier scoring type big. i would personally consider .4 speed a little silly on the high end but i understand why other people could get up there. by the time you get to 0.5 i feel like we are leaving the realm of reasonable - even with all the allowances for various styles and perspectives. i personally am probably in that 0.2 to 0.3 on a top tier scoring big and 0.1 to 0.2 on a mid level scoring big. even fb/fcp i'm not comfortable above 0.3 for a scorer.
