1) Last year, we signed Bradbury, Gibbens and RFA-tendered Elliss about a week into the contract year. I would expect to see similar action before the draft this year, perhaps exactly parallelling with an OL and a couple of defensive front seven players.
2) Of course, there is action during the 2 weeks surrounding the draft, including UDFA's.
3) We also sign free agents all the way up to the "final" cut day and the couple of weeks thereafter. For example, last year we signed Durden, Gregory, DiVito, Woods, and Munford.
