I just started checking the 100M Immaculate Grid rosters. OMG... So many errors. Less than half the teams I've checked so far are legal.

The most common error is choosing more than one teammate per clone. Example: If you are cloning Pedro Martinez (1997 Expos and 2002 Red Sox), you cannot use a teammate from both the 1997 Expos *and* the 2002 Red Sox. And you certainly can't take two teammates from the 2002 Red Sox. It's only one teammate per clone.

There are 9 clones, seven will have one teammate and two won't have a teammate.
