The theory states that the most popular person in many NFL cities is the backup quarterback. For the sake of discussion, let's change the sport to basketball.
Now imagine if that backup is a beloved local kid who has won big at every level and received a hero's welcome back to town.
Godspeed, Ricky Rubio.
"This is a big-boy league," Flip Saunders noted.
Yes, the NBA is not for the faint of heart or mind, and the Timberwolves' incumbent point guard will get a dose of that reality in what already felt like a crossroads season.
Once upon a time, Rubio was the toast of the local sports scene, a young, charismatic novelty with flair to his game.
Now, he'll get to hear how great Tyus Jones is every day.
Jones hadn't even finished hugging his relatives after learning that his pro career will begin in his hometown before giddy social media users started with "Trade Rubio" nonsense.
