Neither will Trance. At best in the NFL he will be a long term back up with zero experience and a lot of potential.

GM's that see potential in a hybrid QB/RB, that has not demonstrated they can actually play QB are luckily to have jobs.
Maybe we should trade up for a WR that breaks a lot of tackles, because they have a lot of potential at RB.
FIRST: That's opinion only. With Rush there are the facts of a 7 year career to look at.
SECOND: There is no logical foundation for saying a player has to be in the USFL to develop. The old school method of having a draft pick QB sit for a few years was always considered the best way, but because of the money involved teams had to start playing QB's earlier.

FOURTH: It's pretty nonsensical to suggest he is just an athlete & hasn't shown traits of a QB given that (A) he threw 28 TD passes with ZERO Int's, and (B) coming out of college he was consistently evaluated as having a very high football IQ and that he is a film junkie who studies the game
FIFTH: It's been consistently proven that college doesn't automatically define a player in the NFL. All players have to adapt to NFL systems.
SIXTH: QB's capable of both running and passing are having success in the NFL. Lamar Jackson, Josh Allen, Jalen Hurts ...
