You are right, but I also consider the difference in the rosters. Richmond was a very talented kid who finally broke out last year. His game this year isn't altogether that different than last. But on the Hall he had the ball in his hands constantly, either operating off PNR or the occasional designed post-up. You don't exactly have an offensive genius coaching over there in South Orange (like Sha, but let's be real). So, the offense was let Richmond have it all the time, and using his passing ability or ability to draw help to feed someone like Dawes or Dre Davis for better looks. Or, when Richmond needed a blow, it was lots of isolation for Dre Davis or PNR for Dawes, who had an excellent year shooting.
He's being asked to play in a different system, with other kids who can handle the ball and make plays.
He's also deferential by nature, and always has been. I'm fine with him not forcing it and playing in the context of team basketball.
He's below the expectations set by some, but for me, having watched him play a lot, he looks like the same guy except at the free throw line, where he is inexplicably significantly below his career average (which was probably close to 75% coming into the season). I don't know the reason for that. I do know that last year he changed his jump shot, and it led to a dramatic drop in his percentages compared to his prior seasons at Cuse and Seton Hall (he was 27% from 3 last year although he took his most attempts ever). Folks are joking that it is because Pitino and the staff have tinkered with his jump shot, but they are far more qualified than me to know if that's better in the long run or not.
He's always been a "fill the box score" kind of guy more than a dominant scorer. I do think he can be a weapon in close games with the midrange or at the rim. We'll see.
Besides the FT %, he looks "looser" with the ball than in the past. But I don't know if that's because I'm watching every play now, as opposed to parts of different games in the past.
