Why we're here in Arizona

PHOENIX -- The NFL annual meeting is taking place over the next four days and we're here to chronicle all the happenings from a Patriots perspective.

This is the time when head coaches from every team host a media breakfast with reporters, and we could learn about primetime games on NFL Kickoff Weekend, as well as the awarding of compensatory draft choices.

It's a time when the owners vote on rule proposals and bylaws, while teams are reminded of 2013 changes such as thigh and knee pads being required for all players.

Here is a breakdown of the rule changes and bylaws to be voted on, in simple terms:

Proposal 1 -- This is specific to the Jim Schawartz challenge in the Lions-Texans Thanksgiving game, when Schwartz threw a challenge flag on a scoring play, which isn't allowed and thus eliminated the ability for officials to review the play. If it happens under the proposed rule, the play would be allowed to be reviewed.

Proposal 2 -- A safety-based proposal which would essentially restrict teams from being able to overload a side on P.A.T. and field-goal block situations (no more than 6 players can align on either side of the snapper).

Proposal 3 -- Eliminating the tuck rule.

Proposal 4 -- Allowing tight ends/H-backs to wear jerseys with numbers 40 to 49. They are currently restricted to 80-89 (unless none are available).

Proposal 5 -- Another safety-related proposal on peel back blocks, making them illegal whether inside or outside the tackle box.

Proposal 6 -- Another safety-related proposal which would make it a penalty if a runner or tackler initiates forcible contact by delivering a blow with the top crown of his helmet against an opponent when both players are clearly outside of the tackle box.

Bylaw 1 -- Altering the waiver-wire rules, where a player claimed on waivers would only have to be on the roster for one day, instead of two, before a transaction could be made.

Bylaw 2 -- Expanding the window to "start the clock" on players placed on the active/physically unable to perform list from weeks 6-9 to 6-11. (Opinion: This is the type of change that Bill Belichick would seemingly like, providing even more flexibility.)

Bylaw 3 -- With this year's season-opening game set for a Wednesday, making the roster cuts to 53 on Friday night instead of Saturday.

More to come over the next few days from Arizona.
