My logic and list goes as follows... which duplicates some people from above in areas. For whatever it is worth... if 50,000 did not chant your name a multitude of times in support & praise - go find another monument.
1. Edgar... Should be unamimous. Is there anyone you would rather see as the face of the Mariners really? Class, proven results, and another reason he should be in the HOF. Only played for the Mariners, gave home town signing discounts, loyalty, and NEVER a blemish.
2. Felix... It will take at least 10 years to build this monument, and by that time Felix will already own every record in Seattle. If Edgar was not here, every word is the same for Felix. Bleeds Blue and Teal. Only wants to play for one team, because the Mariners are HIS team. He deserves this honor.
3. Randy... He was the driving force behind '95. He wanted to be here long term supposedly, but Mariner management would not commit to him due to back issues. When Randy was here though, he was very similar to Edgar and Felix... very Pro-Seattle, very team oriented, and the Mariners were HIS team, and he did everything he could to bring up a championship.
The 4th choice is difficult, and I really do not see a good 4th choice. Just say NO to A-Roid, I really did not like the way Griffey left the Mariners either time he went away, Ichiro never bonded with the city or made Seattle his home, Moyer just does not stand up as a quality choice, and Bruce B was just too quirky and weird to be considered. It is funny that Alvin Davis is NEVER mentioned in this discussion. When does he lose the Mr. Mariner moniker?
By default 4. Junior, but maybe Paxton, Taijuan, Elias, or even Zunino pass him before the monument is completed.
