First 6 games: 19.3 min, 5.0 points, 4.3 rebounds, 3.2 assists, .5 blocks, 2.83 TO's, 3.83 fouls
Last 4 games: 36.5 min, 15.5 points, 7.75 rebounds, 4.25 assists, 1.75 blocks, 2.75 TO's, 3.75 fouls
On a per-36 minute basis, that's +5.96 points, -.38 rebounds, -1.78 assists, +.79 blocks, -2.57 turnovers, -3.45 fouls
The change in rebounding numbers is insignificant with this sample size, and the blocks might be too, but all the other changes are for real. He's playing more, scoring more, turning over the ball less, fouling less, and presumably handing the ball less (thus the fewer assists). Which sounds like settling into a role that he's successful in, instead of trying to flash his skills and getting burned like the first few games.
In addition, Royce only taken one 3-pointer over the last 4 games, which is a good thing. The Vipers' win/loss? 2-4 in the first 6 games, 4-0 in the last 4. I'm certain the people upstairs are real excited about Royce as a trade chip next year.
A significant increase in rebounding rate alone will merit playing time in the NBA at some point (not this season), assuming the other stats from the last 4 games hold for the rest of the year.
