Yes. Try to have a mix of power, speed, and contact hitters. Try to have some y batters, or better still, switch hitters mixed into your lineup. Try to have a mix of right-handed and -handed pitching in your starting staff and your bullpen. Avoid players/pitchers with poor splits, especially the VSR split, since more players are right handed. Pitchers with control lower than 50 are more or less useless, unless the rest of their stuff is lights out dominant. A pitcher with control less than 40 is crap no matter what. Don't neglect defensive ratings, especially up the middle (SS, CF, 2B, C). Try to make sure that your corner in/outfielders are good hitters, or at least good offensive players in some way. Your team should be decent if you get most of this stuff done. I'm sure there are some more rules of thumb, but this is the stuff I go by, with middling success.
