Reports suggested that the Jets' locker room was in turmoil following a tumultuous off-season, which has seen last season's starting quarterback, Mark Sanchez, supplanted by 2013 Draft pick Geno Smith.
Ryan told reporters: "I think I know what the general consensus is out there – but it's not even close. We've had nothing but positive vibes inside our locker room.
"We have way more positive momentum than people give us credit for. We were 3-1 in the preseason, I think that's good. Inside our building it's been nothing but positive."
The Jets face the New England Patriots on Thursday.
