Regardless, he plays behind the best or second best offensive line in the NFL and has two top end receivers.
The Eagles lost Brandon Graham last night for the rest of the year, but no defense has been better than theirs since their bye week in week 5. Their defense removes a lot of pressure.

All things being equal, Hurts isn't a top 15 QB. While playing for his current team, however, he's as successful as anyone in the NFL.
He can't throw on the run. He frequently gives up on plays early. He won't hero-win a game like Josh Allen.

Regardless, he's plenty good enough to win because he has a very, very good situation.
