After a quick look through your league, I think those players should be fine. Some tips for you (some are given out a lot, so forgive me if you have heard them before):
Enthusiasm management is key. TIE against teams you know you can beat easily. Never use CT except for the playoffs.
Start building up your arena. I see you have no luxury boxes. Expand your arena a little bit at a time. Also, your cheep seats look a little expensive.
Get a training schedule. It's not clear to me what you are training based off of your roster. Get 3 decent 18 year-olds, try to get them 48 minutes a week as a PG or C depending on what you want to train, and in 2-3 seasons you'll have 3 guys making 15k+/week
Hope this helps
