Which current NFL QBs could legitimately play another position? Assuming they trained an offseason for it?

I think

Hurts- Linebacker/Strong Safety

Kyler: RB

Lamar: CB, Safety or WR, maybe RB

Herbert: DE

Richardson and Allen: TE

Maybe Allen for DE but I don't know if he has speed for DE.

These are guys with size and speed needed for the positions

edit: If y’all want to include Fields then I’d say RB for him
