Battle and Garcia need to account for about 40% - 45% of our scoring to be competitive. Having a true PG in Ta'lon will be massive in getting them open looks.
We struggled with offensive sets later in the season last year. I felt that Willis not being a true PG hurt us, especially when teams started doing the overly aggressive ball screen hedge at the top of the key. It really stalled the offense, and clean looks were hard to come by. Willis was also gassed, and the defensive effort was often lax (I can't blame him). A true backup PG in Samuels will be huge, even if it is only 8 - 10 minutes per game. We didn't have that luxury last year.
Having a physical presence like Payne will lead to 4-6 garbage points per game and take away 6 - 8 garbage points from the opposing team. This swing alone would have won us multiple games last year.
Scouting reports will be all about limiting Battle and Garcia. All we need from our #2 guard is to hit open shots and play defense. That's what Gabe did his freshman year. It can be one of Carrington/Henley doing this or working as a platoon. From what I've seen of Carrington, he's a high-IQ player, a pure shooter, and puts the team first. I haven't seen much of Henley, but he has some unique physical tools and was reported to get after defensively as a high schooler.
Finally, I think Matz is a good comp for Treyton. If you remember, Matz didn't get any run until later in the season.
Matz: Poor rebounder, non-existent shot, good defensive instincts/shot-blocking prowess
TT: Poor rebounder, decent shot for a big, poor defensive instincts/shot-blocking prowess
If TT can improve to a serviceable rebounder and defender this year, a role similar to Matz is likely, playing spot duty at the 4/5.
