in fact i would be ruthless as a starting team probably all but 1-4 of your starting players are worthless
a good way to start is look at every player whose salary is under $3500 click on them it is says their value is something like "rarely sells for more than a few thousand dollars" or "$1,000-$4,000" I would fire them immediately.
look at your team work out who is your best pg, sg, sf, pf and c that is 5
then who is your best backup guard back up sf and backup big man that is 3 more
finally who are your two best training prospects max 2 if they are not already covered
that is 10 players for the rest if they can be sold for $10,000 or more sell them if not fire them right away
do it you wont regret it
only thing you may wish to check is some guys to see if they are worth keeping with some experts
