This is like laughing at people whose houses got destroyed in the Sahara because they didn't buy flood insurance. Simple probability theory. Intelligent Jets fans understand this concept but are using this particular outcome to rail on the Pats. Keep going.
In theory, the PAT is such an automatic play that no team, ever, would have any reason to put any valuable starters on the play at any point in time during a game. If Gronk got injured on this play in the 2nd quarter when the game was close, would anyone be criticizing? Nope. But theoretically they should be. This is second-grade analysis.
