Smokey the format is fine but ABAA draft puts the B (24th\25 th pick) at a disadvantage.
ABAA will go A= 1,48,49,73 B= 24,25,72,96
for a full 12 rd. draft most leagues use ABBA with one pick throughout entire 12 rds.
Rd. 1 2 3 4 5 6 7 8 (repeat ABBA through last 4 rds.)
A= 1 48, 72, 73, 97, 144, 168, 169, Rd. 9 A starts with pick 193.
B= 24, 25, 49, 96, 120, 121, 145, 192,
This has been the traditional 12 rd. format and I think it's the fairest for all 24 teams
ABAB is what ODL uses with the 6 rd. draft for a 7 player roster + 5 undrafted.
