Just have a look at Patriots joint-practice opponents year by year. Using the practices as a chance to do a little advanced scouting, they've plucked at least one player from every joint-practice opponent they've seen since 2010. Last year, the Patriots worked against the Saints and the Bears. No one remembers former Bears tight end Rob Housler's brief tenure with the Patriots after he signed a future deal with the club last winter. But how about Brandin Cooks? The Patriots got their second close look at Cooks in 2016 -- he was with the Saints during joint practices with the Patriots in 2015 -- and then traded a first-round pick to acquire him the following offseason.
Here's a full rundown of the Patriots joint-practice opponents who were eventually acquired by New England . . .
