As news spread of Andrew Luck’s retirement from the Indianapolis Colts, one of the first people many thought about was former Florida QB Jacoby Brissett. That cause plenty of people to search out his Twitter account and make his deep thought tweets go viral.

Brissett is now one of the most watched quarterbacks in football as he’s immediately inserted under center for the Colts.

Brissett last played for Florida in 2012 as he started four games and saw action in 13 games. He was 41-for-74 passing for 455 yards, three touchdowns and four interceptions. He ran for three scores before he transferred to N.C. State in early 2013.

A sample of some of the recent tweets question whether a dog’s mouth is cleaner than a human’s, what shape is the sky, why lightning supposedly never strikes in the same place twice and what’s on the other side of the black hole.

With more attention on Brissett, look for the quarterback to give some background about his thoughts behind these tweets.

Brissett was drafted in the third round of the 2016 NFL Draft by the New England Patriots. He’s played in 23 games, completed 59 percent of his passes for 3,500 yards with 13 touchdowns and seven interceptions.
