Yes
They have bag check in at outside the stadium. Saw it yesterday at Broncos vs Jets football game.
Yes, you will have to check it outside the stadium
Theres a place out side the stadium at the Verizon entrance they will hold the for a fee.
No they do not allow any bags or suitcases at all. They do have a information number you can call but I do not have it at this time. I know you can look it up or go to MetLife Stadium web site.
I'm not sure a out a bag or coat check at the stadium. They probably have something. I would call ahead though to make sure you can leave a suitcase there during the game. I would be careful too about getting to the airport after the game. That place is a traffic nightmare and it typically takes significant time to get away from MetLife if you drive there. Research taking a train or express mass transit to the airport to save time. Good luck.
