George Kittle's secret golf weapon: Why 49ers star still uses iconic Nike driver from 2014

San Francisco 49ers star George Kittle revealed why he only uses one particular driver on the golf course, while also discussing the gold standard of his position at Tight End University.

NASHVILLE, Tenn. – The final day of this year's Tight End University involved a different sport than football, one that co-founders Travis Kelce, George Kittle and Greg Olsen thought would be the perfect way to build more camaraderie. 

"We did see how Nashville summers are pretty hot, didn’t want to put guys in the fields two days in a row. So, you know what, what’s a way to get everybody around? Golf. Everybody loves golf," Kittle told Fox News Digital before playing at Hermitage Golf Course in Old Hickory, just outside of Nashville. 

It was still a scorcher under the Tennessee sun, but Kittle was ready to go out with his group, which included Kelce, Olsen and his coach, Jon Embree. And they may have needed some ear plugs when it was Kittle's turn to tee up.

That's because Kittle has a certain loyalty to his driver, one with an ear-piercing noise that resembles an aluminum baseball bat rather than today's usual sound coming off the face of a "big stick."

The Nike SasQuatch Sumo2, known more commonly as simply the "Sasquatch," is no longer produced. Its square face and body, mixed with it's black-and-yellow finish, makes it truly one-of-a-kind – much like the man who still wields it today.

Modern golf technology has created better drivers since, but Kittle hasn't wavered from using it since 2014. He explained why.
