Make sure each player is in his natural position. Having Reinprecht at C will give you a lower rating than having him at LW. Also, don't put one type of player on each line (don't make all 3 Scorers or playmakers). Try to mix and match them a bit, with 2 scorers and 1 playmaker. It depends on the person you are using too, so your best bet is to just play around with the lines. When you get an injury, you'll probably have to mix and match again.
These are my current lines followed with their chemistry
Reinprecht Langkow Iginla 100
Gelinas Bergeron Fleury 100
McAmmond Zigomanis Kobasew 80
Sejna Lombardi Donovan 100
Clark and Simon are my fill ins.
Leopold Boynton
Regher Ference
Warrener Montador
