I've had 6 teams end in the last week...69, 85, 86, 88, 90, 90 wins. I have others currently going on pace for the playoffs, others with no hope.
I used to be like you, I think. I'd go with guys I liked and thought SHOULD work, and I always did crappy. Though my rating still doesn't reflect it, my most recent 50 teams (out of 179) have probably accounted for half my playoff appearances because I started paying attention. I don't analyze it the way some do, because I want to keep it fun, which is probably why I'm still not an elite owner, but I'm okay with that.
The difference now is, I pay a little more attention to stats and I go in with a strategy based on what kind of team I want/my ballpark, etc. Sometimes it's feast or famine, but that may be a risk you have to take against good owners.
If you're really frustrated, join progressives. Everyone's in the same boat early, and drafting and management play a huge roll.
I'm a very vocal advocate against the recent streakiness of the SIM, but it would be WAY to hard for them to coreograph everyone's win totals.
