At lower levels it's easier to get by with defence, which you don't seem too keen on judging by your game ratings, game scores, and marketed players (being a C with pitiful ID and a PG with atrocious OD). I had a similar mindset last season and it didn't work for me. I'm still working on changing it but it takes time, it's fixable. Working on your game shape should also be a priority. Roster 11-12 players and properly manage their minutes. Here's a graph displaying the relationship between minutes and game shape:

It'd be optimal for you to overhaul most of your roster at some point. Especially if you currently have a high percentage return on your marketed players. I could try to help there, but I'm pretty new also.
And I guess I should post something pertaining to the intended use of the thread.. it's hard to say how I'm doing because my IV league is infested with bots. I'm improving every week I guess.
