nice job! that team is about as fast as i've seen, overall. i think central in d3 tark might have had a couple teams slightly faster, or at least, right around there, about 5-7 months ago. they one multiple championships with those teams though, so there would be no shame in being slightly slower ;) i would be surprised if any team this season was faster though. im not sure you can build a quality d3 team that is more than slightly faster than that overall... i surly haven't seen the players for it, at least :)
on the other hand, i would say weighted speed, you can see a little faster (although your teams still has GREAT weighted speed). by weighted, i mean that guard speed should count for more than big man speed, because it is significantly more important. i had a howard payne team a couple seasons back that was decently faster, weighted, IMO. their guards were actually noticeably quicker (and there is certainly room for more speed in your guards), but their bigs were a good bit slower. thinking back to the other top teams that year (that was the last time i played d3), i would say yours was at least on par with the fastest teams, weighted. so i would think this year, weighted speed, there might be a couple teams in your stratosphere but i doubt anyone has you beat by a meaningful amount.
