Deion Sanders once had maybe the best line ever about loyalty in sports. It's succinct. It's beautiful. It's also incredibly true.
"It's hard for me to fathom," Sanders said not long ago during a player roundtable discussion, "that I gotta be loyal to you, when you're not loyal to me."
Sanders later added: "I can't love nothin' that can't love me back."
This brings me to Colin Kaepernick, who was just benched by the 49ers and almost certainly will be playing elsewhere next season, likely in a place like Philadelphia.
Kaepernick never learned the lesson that Sanders did.
