One thing I really like about this game is that 2-star players can make a meaningful difference in your success. It might be a 2-star PG that only averages 7 pts and 3 assists but I feel like they actually make a difference. This doesn't apply if you're trying to make a super-team, but for your average 4 seed in the playoffs I really feel like my bench makes a difference. I think some of this may be due to the endurance/discipline rating on youngsters being so low for a couple of seasons, so you really need a decent bench to supplement these guys.
I've had some 2-star players put up a 15-5-5 season (granted they were bad teams), but it happens. I'm absolutely having a blast playing this game.
