Just to be clear, this rule would only mean that the same owner can't have both of the same guy? In other words, there would still be two Yakes, but they would have to play on separate teams, right?
The original intent of this league was to keep the game as close to the original as possible with the exception being the drafted rosters. Having two of the same guy in the league, albeit not on the same team, was one of the quirks of the original game, which is why I felt that both should be included.
All-stars will not be included, sorry.
