Yea, but just because all the cool teams are doing it. Mariano Rivera is the only guy left that can wear #42, right? Personally, I think retiring 42 for all 30 teams was ridiculous. The only team that should have it retired is the Dodgers. Let players wear it on the other 29 teams to honor Robinson. Pardon my stupidity, but was retiring 42 for all the teams another one of Bud Selig's bright ideas? Yes.
