I think that misses the point on Josh Allen by a country mile.
The arm strength is fantastic, obviously. But that's not why he's rated high. He's rated high because HE MAKES PLAYS. His reel of A+ plays stacks up next to the A+ reel of any QB that has ever played the game.
It's not about arm strength. That's such a simplistic way of looking at it. Making big plays is about size, strength, feet, mentality, vision, accuracy, and yes, arm strength.
Last year when he had a good ground game (this year it was awful, he had to carry the team by himself, and in a pro style offense that's a big disservice), I thought he made good decisions. Good balance between making plays nobody else can make, and taking what the offense wants to give you within structure. This year at times that went off the rails a little bit.
People are talking about this guy as if it's all arm strength and size. It's not. He's closer to a Johnny Manziel or a Patrick Mahomes as a prospect than he is a Ryan Mallett, Brandon Weeden, or Davis Webb, big guys with fantastic arm strength.
Except unlike Manziel or Mahomes, Allen has been working in a pro style system and has a head start on a bunch of other players.
The guy that was pretty much Mr. Preseason this year was Cooper Rush with the Dallas Cowboys. He was a guy that had the physical tools, but really the most outstanding part of him as a prospect was just how translatable he was to an NFL offense based on what he was asked to do at Central Michigan (under John Bonamego, who used to be on the Dolphins coaching staff). He gets over to the NFL and at least during preseason work he's outstanding. But he has just average to maybe even below average physical tools, very little play making history. Josh Allen has tools, and he's been making truly jaw-dropping plays.
Carson Wentz is another example because when he came out the things he had going for him out of NDSU (we're talking 1.5 years experience at an FCS level football program!) were that he had an outstanding physical tools profile, really good interviews, came from a pro style system and knew all kinds of things other prospects didn't, won football games, and made plays.
Well in comes Josh Allen, who played at Wyoming (not a great level of football either, but a sight better than North Dakota State), has two years starting experience, played in the same pro style system as Wentz, has an outstanding physical tools profile, makes plays on tape, and supposedly is an outstanding interview (has been interviewing for pro teams since last off season and that's the reason he's been rated so high).
I laugh when people try and differentiate Carson Wentz from Josh Allen as if it's soooo obvious they're so different. As prospects, no they're not. Carson Wentz threw 62.5% completion his last season at NDSU versus Josh Allen's 56.3%. It's not as if Wentz was one of those 75% completion guys you see (almost exclusively in spread systems). Wentz threw for 1651 yards, 17 TDs and 4 INTs his final year. Allen threw for 1812 yards, 16 TDs and 6 INTs.
