uglyskunk provided some sound advice re: recruiting players with a WE below the mid 30s is not going to be so good now, and sticking with fairly fresh for stamina.
burton is right in that slow down would be the way to go with some many underclassmen (9) and poor stamina.
as far as lineup goes, i'd go with this:
PG - Owen, Hull/Brownell
SG - Tinney, Plata, Brownell
SF - Marshall, Hull, Tinney
PF - Lindsey, Poor, Klinger
C - Cadiz, Drain, Klinger
PG /SG - I think you have to start Owen & Tinney at guard. you always want your best BH/P as your starting PG, and Tinney's stamina alone makes him a better starter than Plata.
SF - you could make a case for starting Hull because of IQ, REB & P, but SF's w/ ATH/SPD tend to excel. Marshall is going to be very good, i'd get him the minutes now (although his stamina is very low)
for PF/C, everyone has a similar skill set. you might actually want to bench Klinger to get the young guys some PT until the CT. outside of passing & IQ, i'm not sure he offers anything that the younger guys can't provide.
hope this helps!
