George Kittle stood on the sidelines in the final moments of the 49ers' heartbreaking loss to the Kansas City Chiefs in Super Bowl LIV. He kept his helmet on, still ready to play, and let his mindset be known: I will not let this happen again.

"I will be back here," Kittle said while mic'd up on Showtime's "Inside The NFL." "I will be back here, and I will be back with a motherf---ing vengeance."

Speak it into existence king.

The 49ers' All-Pro tight end caught four passes for 36 yards in the loss. He also was flagged for a controversial offensive pass interference at the end of the first half that would have put San Francisco in scoring position. The play would have resulted in a 42-yard gain and put the 49ers at Kansas City's 13-yard line.

Earlier in the show, Kittle is shown disappointed as Chiefs coach Andy Reid changed his decision from kicking a field goal on fourth down to going for it and trusting his elite offense.

"They're going for it?" Kittle is seen asking. "Damn."

Always do what your opponent hates.

If you're going to be kicking field goals instead of getting in the end zone, you're probably coming out on the losing end against the Patrick Mahomes and the Chiefs. The 49ers found out the hard way as they blew a 10-point lead in the fourth quarter and allowed 21 unanswered points.

Kittle was a first-team All-Pro and made the Super Bowl in just his third professional season with the 49ers. There's no doubt he'll be coming into next season with revenge on his mind.
