Berry started at PG in the scrimmage at the end of practice the other day and looked very, very good.
I truly don't expect Theo to be much better than what level he was at when he got hurt. He simply hasn't been able to do much of anything since, he was limited all summer to take just shooting around (jump shots not permitted) . . and he's still being held out of any contact drills. Hopefully, he'll make those improved playing skills that we expect from 1st year to 2nd year as the season progresses.
As for who starts, that matters little, as Roy will play the better players more minutes regardless . . as Theo improves, he'll get extra minutes. We should all be praying that Justin Jackson stays healthy this year, as we are extremely thin at the SF position until Theo can return to 100%.
