Before the UNLV game, they were 5th worst in FT shooting in the entire country. Those other teams you’re comparing them to are hitting them at (often) a much better clip. We need more practice than them.
If you think being 348 out of 352 teams in any statistical category is something that you don’t need to practice more, I don’t know what to tell you.
Whether it’s a practice thing, a mechanics thing, or a psychological thing, waiting until the holidays (as stated during the game) seems like an odd take. Rebounding has gotten better the last few games, so it seems he’s been focusing on that. Things can get better if you focus on them, but hey, just keep ignoring it and wait until it legitimately costs you games.
