The point of Andy's 'cuteness' is to show defenses so many looks they can't plan for everything. For 17 games they had Kelce line up behind center only to run the ball for a first down or a TD.
Now when he's behind center, they know there's a legit chance Travis can throw for a TD. This makes it a bit easier for him to run the ball, like in the last 17 games. One play opens up the next variation.
Sometimes the defense guesses right, sometimes they execute well. When that happens, it's more difficult to succeed. And that's gonna happen... it's the NFL.
They can't be successful every single play. But all these options, formations, reads, personnel, etc make it harder for defenses to gameplan which increases your odds of success.
That's the benefit of having so many talented players.
Frankly, being as how Kelce was a college QB, I'm surprised he hasn't been given the green light to throw the ball more.
I'd love to see a jet sweep option with Kelce in motion, who can either run the ball or stop and throw to a wide-open Mahomes.
A guy can dream.
EDIT: I have been frustrated with his 'cute' playcalling at times too. But I'm just an armchair beer drinker. Andy's the best guy to be calling plays.
