I started to post the rules, and decided not, too.
The truth of it is that at the Senior Bowl and at the Combine there's some wheeling and dealing already happening.
In other years, Les Snead was knee deep. Have no idea what the style is he had to adjust too this year. Narrower window.
The reason I didn't post the rules is that other than the "official" date the rage is already on to acquire or excise rosters.
"Contact" with agents prior to "open season" is disallowed, but it's pretty much not obeyed
Friendly discussions are well under way; to be sure. Shopping players, trades, etc
In fact, some of the discussions probably aren't that friendly. Players unhappy with their lot are seriously adding friction to their camps.
For us, I don't expect a trade to happen, but the drama will involve who we don't sign
Some terrific posts by many here on the topic
