Ok st isn't big in the frontcourt, or even really in their starting lineup.
These three guys have started all their games:
Obi Muonelo - G - 6-5 (25 mpg)
James Anderson - G - 6-6 (33 mpg)
Marshall Moses - F - 6-7 (29 mpg)
Three other guys have started games:
Matt Pilgrim - F - 6-8 (2 games, 14 mpg)
Keiton Page - G - 5-9 (2 games, 31 mpg)
Ray Penn - G - 5-9 (3 games, 28 mpg)
Fred Gulley - G - 6-2 (1 game, 22 mpg)
Only one other guy plays more than just a few minutes per game:
Roger Franklin - F - 6-5 (12 mpg)
Based on minutes played and starts it looks like Ok St's starting lineup could be:
Keiton Page - 5-9
Ray Penn - 5-9
Obi Muonelo - 6-5
James Anderson - 6-6
Marshall Moses - 6-7
They do have 3 6-10, 6-11 type guys who apparently never play more than a couple of minutes at a time.
I think a lineup of:
SM 6-0
AW 6-5
CR 6-4
TB 6-7
WE 6-9
will be able to compete just fine from a size advantage.
And I think a "3 bigs" lineup could be a total disaster against this team that based soley on the size of it's players and their lack of 3-shooting is probably a big time quickness and slashing team.
