Bad luck : good news you did not pick these players. If you have three speedy guards, good def and ath, you go 3-2. If you have a Sf, good passing one 30+, but build in a pf mode, you go 2-3. Basically, you need 5, pf,c to fill 3 positions, and three guards for the pg, sg spots in 2-3. It's the other way around for 3-2. I am starting the same thing as you in Lakeland, my recruiting was awful but I had to go 3-2 cause I lacked talent upfront. Here are the minimum stats to shoot for when your player is a senior.
3-2
PG ath 40, spd 70 def 50 bh 70 pass 60
SG ath 40 spd 70 def 50 per 80 bh 70 pass 50
SF two types ath 45 spd 55 def 55, per 70 bh 60 pas 40
PF ath 55, reb 75, blk 70, def 55, lp = bonus, pass = bonus
C ath 50, reb 80, blk 80, def 50, lp = bonus.
if you get that type of talent, you will start to compete, after that you need to learn how to hide weaknesses and to recruit better recruits than the minimums I showed you.
In 2-3, you basically need to put a slightly better PF at SF, but do not underestimate sblockings and rebonds in zone... really key.
