At least it looks like his non-throwing arm.
This is the one time where the league's ability to keep players for years and years might help us. He's got the 4 year contract, 5th year option, plus they can franchise him in year 6 and even into 7, though that gets reaaaaal pricy real fast. Considering he came into the league a little older, he's gonna want to sign a big deal early, vs letting a team jerk him around until he's on the wrong side of 30.
I don't think he'll want to leave though. Myles Garrett chilled out and signed a new deal in Cleveland, he just had to be shown the money. Jayden is gonna get a huge pay day in a couple years.
