I can. First, it's only day 1. Plenty of quality free agents still out there. Two, this is usually the day a lot of days goes crazy and overpays for a player that doesn't deserve the money. Third, this team is still has a lot of holes, so there's no need to go on a spending spree and panic to try and fill those holes. Bad teams do that. See the Redskins and Raiders. Good teams build through the draft and supplement their roster in free agency. The teams that usually "win free agency" don't go very far. Fourth, it's not surprising it was a very quiet first day given the history of Idzik. Dude is patient as hell, so he is not going to make any brash signings for the sake of signing someone. And the free agency class is mostly filled with second tier players to begin with. The top name was a safety for god sakes. There's still plenty of time for the Jets to make moves. But they have to be smart ones.
The dude's been in the NFL for 5 days and the media is already killing him. Let the kid play a damn down and see how he deals with things then you can criticize him all you want. The New York media and the media in general have a problem speculating and trying to guess what kind of person a player is. It's so dumb and causes unneeded drama.
