I know that the 3k cut off is the go to advice on the forums, but I don't think it's particularly good advice for brand new, bottom of the division players. Most likely 2-4 of your players are only going to play in the scrimmage at the end of the week - why bother having guys with $3k-4k salary playing garbage minutes when $1.5k guys can fill in just as well?
or the 18 year old hall of famer, who gets fired because of such advise :)
