The college football reference website is useful, but not complete. I've gone back over UM rosters going back 40-50 years--and I remember, to some extent players and our teams over at least that long. I've seen what I think are incomplete rosters. Still amazing to see those old names, but perhaps not complete.
I did find, for example, Daytona Cane's late husband, Doug Davis, from the '58-'61 era. I do remember him, but not as well as some others. I remember most of his teammates from that era.
You might think that all players' names can be found on old rosters, media guides, or game programs. Not true. I've met guys who were on the team, dressed out, but we're not listed on the media guide and possibly not in game programs. If I get a chance when I get to my computer ( and not my phone) I'll write about a player I knew who was in that category.
