This is the Mathews trade, its not like your describing at all
26. Patriots (Trade down to Packers)
Packers receive:
•2009 first round pick, 26, pick LB Clay Matthews III
•2009 fifth round pick, 162, pick tackle Jamon Meredith (later released by Packers)
Patriots get:
•2009 second round pick, 41, pick DB Darius Butler
•2009 third round pick, 73, pick DB Derek Cox
•2009 third round pick, 83, pick WR Brandon Tate
Patriots trade Cox to Jaguars.
Patriots get:
•2009 seventh round pick, 232, pick WR Julian Edelman
•2010 second round, 44, traded that pick to the Raiders for 42 to pick TE Rob Gronkowski
(Raiders get second-round pick, 44, DT Lamarr Houston; sixth-round pick, 190 pick LB Travis Goethel)
So, basically, you could have either Clay Matthews, or Darius Butler, Brandon Tate, Julian Edelman and Rob Gronkowski. (Though the Patriots probably still could have made the Gronkowski trade among other moves).
