Looks like you ended up getting a team with a lot of dead weight.
You only have one scholarship offer for next year, so this will be tough.
Try to do what you can to boost your preferences, this year, perimeter shooting, playing a certain type of offense/ defense and try to target a couple of recruits with high potential.
At the end of your season and between the 1st and second recruiting period, you can rescind scholarships. Start with freshman and work your way up, so you don't end up with those players for several years. Rescind as many as you can, so you can get the resources for the following season.
