Question about subs

[---]

Hey everyone i just need to ask a question since i hav bought 2005 and am just waiting for my computer to get back (it crashed and i lost EVERYTHING) in nba live 2005 in season (or dynasty wateva it calld) do the subs on all cp teams usually only play about 5 mins per game and they all average about 2 - 3pts? because i had this problem on 2003 and it really sucked
