I do. Just keep putting the numbers up on the wall like they do now, but leave them in circulation and don't call it a number retirement. Call it something else -- the Kings of Queens, the Diamond Club (that's probably already some bar in Citi), the Ring of Honor, something. Retiring numbers is such an unnecessary, largely American tradition with no set standard, so clubs do it just because other clubs are doing it. Retire all the Joneses to keep up with the Joneses.
Plus, we're depriving ourselves of some cool shit. What if we ended up with a bunch of great left-handed starters who all wore #36? What if they had issued Doc #41? What if Olerud wore #17 cause he loved Keith? Number lineages are waaaaayyyy cooler than retired numbers.
Leave 42 retired (I'm good with that) and put 'em all back in the rotation.
