I would personally need specific skill sets and such to give you a detailed analysis of what i like and dont like.
However, what can be said without anything is that you aren't managing gameshape properly. You have starting caliber salary wise that are at 6's in GS. I usually have most starters @ 8 GS, some in the 9's and a few occasionally dip to 7 in tougher weeks.
I'm not as worried about your mass of younger talent. I assume two are random fillers for depth on the roster.
