Players that made a big impact that are less remembered:
Don Baylor (of all the impact guys on the 86 team, he's probably the one people don't think about)
Greenwell (people remember him, but don't remember how f***ing great he was)
Boddicker (key in the stretch run of 88 after coming over from O's)
Jody Reed (important member of the 88 and 90 teams)
John Valentin (perennially underappreciated leader)
Bret Saberhagen (really great in 99 when healthy)
Reggie Jefferson (peaked in non-playoff years and is forgotten)
Carl Everett (greatest hitter alive the first half of 2000)
Mueller (we all remember him, but he had so many clutch hits in 04 and the second highest oWAR on the team in 03 too)
Scott Williamson (dominant in 03 postseason, great in 04 before injury)
Okajima (dominant in 07 and 08, mostly forgotten due to the run of other notable Asian relievers afterwards)
Mike Carp (OPS+ of 139 in 2013)
Craig Breslow (remembered because he was an ivy league guy, not because he pitched a 229 ERA+ in 13)
RHB bench bat Rick Porcello (OPS+ 201 in 2018, slugged a redonkulous .714 when he wasn't striking out 43% of the time, that's Dalbec in single A numbers folks)
