Tre and Cam will be our "game-icers." But yes, to me it's a concern as well.
Grayson and Trent were both better FT shooters than Tre/Cam will be.
Grayson/Kennard were also about as good as it gets.
We also had the year where Quinn and Tyus seemed to not miss a clutch FT for an entire season.
AOC and Baker could also be clutch FT shooters in big situations, I trust both of them at the line.
Another thing on RJ...he's gonna live at the FT line, probably have a similar amount of attempts per game as Bagley did, while probably only shooting a slightly better % than Bagley. However, I've always felt that the more attempts you get a game, the better off you are in clutch situations, so I feel pretty good with RJ too.
Bagley was pretty good on clutch FT's from what I recall, I remember quite a few big situations in the PK80 and he was money.
