I was just using two as an average. Obviously teams like the Pats and Vikings have a handful of 95+ players, but others teams may have 1 or 2, and quite a few will have none.
From my impressions rating a team, there aint that many teams in the league with more than 2 superstars.
For example the Colts. Peyton Manning 99 for sure. But you could put Wayne, Sanders, Freeney, Mathis within +-2 of 95.
Depends how generous you are with ratings.
