My players havent started declining yet, thank god! I know the time is coming tho. As for the mix thing goes, you could have the perfect lineup, they just need more work done. When i picked up Romeo whatever his name is in 2015, i got him only for 63 800 he wasnt half the player he is now. Lee quick took about 4 good seasons, ed, took the same, with albert i just worked on his rebounding. The goal was to at first have a inside team, but my players changed that idea. So we became a outside middle team with speed. So albert was just good for rebounds, and a couple of shots that he decides to put up.
This lineup i have now, took us a few seasons to even make the playoffs. There were alot of good teams here, when the Foes showed up. The point is, its to early to tell if u got the perfect starting 5. Plus the league isnt as strong, so you got time
