Josh Allen is a fine player, but I do not ever see him passing Mahomes (baring injuries of course, that is the wild card in this game) It is not his play making ability with his legs that makes Mahomes so great- a lot of it is his ability to create when plays break down- avoiding pressure, throwing accurately on the run, no look passes, he can change his arm angle to avoid defenders and still deliver the ball downfield where it needs to be... He is a magician! Josh Allen is a little bigger guy and might be able to throw a LITTLE harder/farther, but I would argue Mahomes is more accurate even on deep balls. JMHO
in fact, Josh Allen as recent as last year was ranked among the least accurate passers in the NFL:
Tom Brady’s is the NFL’s greatest quarterback, but is he its most accurate? PFF has the numbers.

He may have a “big” arm and I am sure his accuracy numbers improved this year dramatically, but accuracy is more important than ball speed generally speaking...
