NFL mystery: Where are the left-handed quarterbacks?

When Tua Tagovailoa signed his rookie contract with the Miami Dolphins, the left-handed quarterback out of the University of Alabama didn't have to worry about smudging his signature.

He signed the documents with his right hand.

Yes, the NFL's latest lefty QB is a natural right-hander, one whose father, Galu, turned him into a (sometimes) southpaw in his youth.

"My dad was the only lefty in our family, and he wanted me to be a lefty as well, so he switched the way I threw," explained Tagovailoa, who still eats, writes and plays golf right-handed but shoots baskets and throws footballs with his left.

"I don't think I would be here if I was a righty," said Tagovailoa, who was selected No. 5 overall despite an injury-shortened 2019 season with the Crimson Tide.
