No. Just an example of someone who took two untouched blitzing hits from Buffalo and was fine.
Phenomenal play by Watson. Really top tier stuff. It's one of the reasons that he was/is a top 5 QB. But it doesn't prove or disprove anything about Tua's "fragility".
1) Watson doesn't get blasted in his ribs
2) Watson doesn't have the full weight of a 300 pound defensive lineman drive him into the ground on his ribs.
It's fine if you or anyone else doesn't like Tua. I don't like or dislike him yet. But that hit he took was wicked (albeit clean and completely legal). If you think that most QBs would've gotten up from a hit like that unscathed, then you're being intellectually dishonest. A taller, larger framed QB may absorb that hit. And while they may not sustain a rib injury (because the target area would be different, due to height), they may sustain a much worse injury, such as a clavicle, collarbone and/or shoulder, due to being driven into the ground. It's happened many, many times in the past, and it's part of the reason for the rule changes protecting the QB.
I guess what I'm saying is, you can dislike a player without making hyperbolic statements to drive home your point.
