in my opinion, no. i havent seen any evidence that the HCP does a damn thing. i used to count the turnovers from double-team, trap, press - a while back - it was under 1 per game, in the game logs. which may not reflect the full impact but i checked like the entirety of the 15 teams i could find who played, and saw no higher turnovers than i would expect, from a non-press set, at least not more than ~1 per game. i thought my margin of error was maybe ~1 per game back then and i saw maybe ~.5 per game increase. so i guess it could be a little more than 1, but i really doubt its much more, if at all. just not worth it, IMO, costs you stamina. screw practicing it - even if you practice - id go straight press or straight non-press, with that IQ. just not worth the lower fatigue for 1 extra turnover (woo!)
