Backup QB Nassib continues to struggle with Giants

Never mind the Giants’ No. 2 quarterback job.

Ryan Nassib appears to be struggling so much in offseason workouts that the Syracuse product might need a terrific training camp and preseason just to keep his roster spot.

Nassib had another bumpy organized team activity on Thursday, throwing multiple interceptions — including a pick-six — in 11-on-11 drills and generally looking lost in new offensive coordinator Ben McAdoo’s scheme.

The Giants seemingly couldn’t have made the path to Eli Manning’s backup role any easier for Nassib, even cutting former Buccaneers first-round pick Josh Freeman recently.

But Nassib doesn’t appear to be separating himself from the ailing Curtis Painter, leaving the 2013 fourth-rounder’s future with the Giants in question.

“It’s definitely a process, and it’s coming along slowly,” Nassib said Thursday. “They’re putting in new stuff every day, and it’s all about learning it as quickly as you can. It’ll take some time, but it’s coming.”

Nassib’s problems stem mostly from his skittishness in the pocket. He has good size at 6-feet-2, 225 pounds, and a cannon arm, but anything resembling a strong rush often seems to result in happy feet, a short-armed throw or a poor decision.

Ryan Nassib.

Nassib didn’t take a single snap in the regular season last year, even while Manning was enduring his worst season as a pro, and hasn’t appeared to make much progress since scuffling through the preseason as a rookie.

Nassib completed just seven of his 19 throws (37 percent) for 114 yards and no touchdowns last August while absorbing five sacks.

Thus far, Nassib is making the Giants look bad for their middle-round flyer while making former college coach Doug Marrone — now with the Bills — look good for choosing EJ Manuel over Nassib last year.

Nassib told The Post on Thursday he was hurt by Marrone’s snub but has since patched it up with his Syracuse boss.

“I understand now,” Nassib said. “It’s just business. It wasn’t personal or anything like that. I ended up in a great situation where I can sit and learn from a two-time Super Bowl [MVP] in Eli.”

But if Nassib feels frustration about ending up with a team where winning the starting job always has been completely out of the question, he hasn’t shown it.

“Being a competitor, you want to get out there and play and compete,” Nassib said. “It’s also good to sit back and learn and develop, because there have been a lot of great quarterbacks who sat their first few years. I’m extremely happy with what’s going on here.”

Whether the Giants feel the same way could be answered as soon as this summer.
