I'll have to take another look later, but at first look, I'm not sure if I would count this in the same league as some of the other bad interception plays I've seen. It looks like the QB waits a split second too long and lets the defender get the jump on the pass.
It's not a smart throw, but I don't know if it's egregious as some of the other INTs I've seen (like when a QB rifles the ball to a DE/DT or throws it into triple coverage while ignoring three open WRs).
That's what makes this thread tricky though. Knowing what plays are plays that need intervention and what plays are good defense.
