My vote process between Collins and Morgan:
Major stat categories
Morgan, 22 Seasons, .392 OBP, .427 SLG
Collins, 25 Seasons, .424 OBP, .429 SLG
SB, CS, RBI, Runs are equal
I'm not going penalize Joe for only playing 22 Seasons, so this is pretty well a draw.
One point of reference is baseball-reference.com's Black Ink, Gray Ink, HOF Standards and HOF Monitor and Collins beats Morgan in every category... Statistical Manipulation edge to Collins
But I like to look at MVP voting along with stats, Morgan has 2 MVPs, Collins 1.
Collins finished top 10 7 times (1 1st, 2 2nd, 3 3rd, 1 5th and a 6th), Morgan 5 (2 1st, 2 4th and an 8th).
One of Collins 2nds was to Ruth in '23, the other to Walter Johnson in '24. His 3rd place was behind Johnson and Joe Jackson in '13 and Ty Cobb and Ed Walsh in '11
Slight edge to Collins IMO.
Both managed a couple of years
Collins 174 W, 160 L, .521 PCT
Morgan 301 W, 262 L, .535 PCT
Morgan also took the Red Sox to the Postseason, but has no more postseason wins than Collins.
Slight edge to Morgan.
How to decide, well I'm pretty sure that Collins is a better announcer.
So there you have it. Collins. One man's vote
