Williams: This offseason has been among the most active in NFL history

Key notes from Charean Williams interview

• It's been one of the most active free agencies we've ever seen. We haven't seen the Tom Brady types move around like we have this year. We had a historic day earlier this offseason when Tom Brady, Phillip Rivers, and Jason Witten all left the only teams they've known on the same day. It has been strange because most of these deals are not even official yet with many physicals still outstanding.
