So if you look at Avery's stats he's having his best year.
He has been playing 28+ mins/game since the 2012-13 season, meaning this is his 4th year doing that.
His minutes are actually down slightly from the last two years, but he has (barely) a career high average in points and assists. He has a career low in fouls (since 2012-13...everything I am saying is since then. I'm not counting his first two years. I'm counting the years he was a solid rotational guy), and kept his TOs steady. He also is averaging a career high in steals and his rebs are staying steady at what they were last year, despite playing less minutes than last year.
The major reason for his excellent play is a career high in fg% and a super career high in 3pt fg% (although he has dipped a good deal in FT%). That means this is as good as it gets for Avery. He has largely peaked and I think the reason is that he has been moved to the 6th man role that he is excellent in. He gets to come in and crush the other team's 2nd unit with his smothering defense and keeps the offense going.
They need to keep him there. He is not a starting sg, and certainly not a starting pg. He is a combo guard 6th man defensive specialist extraordinaire, who get's paid reasonably. He's kinda Tony Allen when Tony was close to his best.
He's the kind of player every coach would love and would want.....playing a leading role in the 2nd unit.
If they were ever going to trade him (not advisable) now is the time because there is no way they could expect him to keep up the shooting percentages he has right now.
If they keep him in the 2nd unit it is best because it allows Smart to grow and allows IT to maximize his value. That's why Rozier should be starting now. Let Rozier learn. Let Avery be at his best.
