the guy i sold last night... Dihong.... had resp stamina (by far the most in my team... check out his PF column... he had shirt number 70 for a reason.... that was how many PF last season (comp games only of course!)
.
I dont notice my players giving away more fouls than on average and my OD, ID & SB varies wildly across my players..... id be interested to see evidence supporting your theory... or in 1-2 seasons time ill confirm it myself if i ever get around to stamina training!!!
