Travis Kelce's acting career has taken off this past year, but it's NOT the direct result of his relationship with Taylor Swift ... so says "Friday Night Lights" actor Sinqua Walls,who tells TMZ Sports he's gettin' gigs because he's a natural talent -- but being a 3-time NFL Super Bowl champ doesn't hurt, either!!
The 39-year-old actor -- also known for his leading role in the "White Men Can't Jump" remake -- broke it down for us this week ... shortly after he drove by a billboard for "Grotesquerie," a new horror TV series featuring Kelce.
