The NFL is back, and so if Fitzmagic.

The biggest first-half shock of the early slate of games Sunday is Ryan Fitzpatrick’s Bucs, playing without Jameis Winston and without fear.

Playing in New Orleans, 9 1/2-point underdogs, Tampa Bay raced to a 31-24 halftime lead behind perfect play by the 35-year-old former Jet. Fitzpatrick went 11-for-14 for 210 yards and two touchdowns through the air in the half — plus a bruising touchdown on the ground, trucking safety Marcus Williams.

The prettiest throw was a 58-yard bomb to DeSean Jackson, the Harvard product looking off the Saints defense and then unleashing down the right sideline to a wide-open Jackson.

We’ll see if it’ll last — Fitzmagic lasted 15 weeks with the Jets in 2015 — but it’s a fascinating start to Week 1.
