Is Joe Burrow the last one?
I'd say he's a dual threat qb
“Dual threat” implies there’s a possibility he’ll run as often as he throws.
Luck threw on 90.8% of his dropbacks (3290 pass attempts to 332 rushes) and ran on 9.2% of them.
Like Luck, Mahomes literally throws the ball 90% of his dropbacks (2993 pass attempts to 299 rushes) and runs on 10% of them.
9 passes to 1 rush attempt does not make them “dual threat”. They’re mobile pocket passers.
Meanwhile Jackson throws on ~69.5% of his drop backs (1655 pass attempts to 727 rushes) and runs on 30.5% on them.
That is a dual threat QB.
