Travis Kelce better prep his monologue ... 'cause "Saturday Night Live" alum Taran Killam tells TMZ Sports the NFL superstar would be the perfect pick to host the comedy sketch show!!
"Travis Kelce is one of the funniest, coolest dudes and a legend," Killam said at LAX.
"It's just not fair to be that strong, fast, good, charismatic, handsome and hilarious. I hate him. He's coming for my job," he joked (or is he?)
Killam knows about both comedy and football -- he actually has an Amazon Prime show, "The NFL Pile On," where he puts a funny twist on the sport's biggest stories of the week.
