Edgar - seriously, probably the only unanimous choice here.
Junior - probably responsible for the creation of more M's fans than any other player.
Ichiro - I get G's point but he played in Seattle for over a decade and had a historic impact in a number of seasons.
Felix - Perhaps a little premature but he's already given the club more excellent seasons than any pitcher in club history.
I love Randy Johnson but he has already said that he will go into the HOF as a Diamondback, as he should. He was became great in Seattle but took it to another level for Arizona. I can't put a guy on the M's MtRushmore that would also be on another MLB team's MtRushmore. Armstrong will always be in my hall of shame for running RJ out of town the way he did and depriving us of his peak.
