The rookie quarterback, chosen in the fourth round, came out strong on Friday in favor of Rex.
"(He) might be my long lost dad," Jones said, per ESPN.com's Mike Rodak. "I've been looking for him 23 years and I found him."
The pairing of Ryan and Jones should be fascinating to watch. Like Rex, the former Ohio State passer is known to speak freely and shoot from the hip -- not always to glowing results.
Beyond operating as a quote-machine, Jones joining the Bills raises another question: Could he wind up starting as a rookie? Tyrod Taylor looms as the team's clear No. 1, but until he shows supreme durability, it's fair to wonder if Jones could hopscotch the ineffective EJ Manuel to see meaningful snaps if disaster strikes.
With Ryan and Jones both harboring dangerous man-crushes for each other, anything feels possible in Buffalo.
