Giants’ Gunner Olszewski surprises with stunning grab to kickoff injury return year

Jameis Winston led the second-team offense down the field for a touchdown drive during 11-on-11s, completing pass after pass to … Gunner Olszewski?

Who would’ve predicted that?

The receiver/returner was the star of Monday’s practice, hauling in four catches on a single drive. That included a stunning grab while leaping nearly horizontal in the end zone for the touchdown.

“It’s most important what you do with the opportunities,” Olszewski told The Post after practice. “I haven’t had many, and I haven’t taken advantage of the ones I have had [in the past].”
