In my free agency day 4 wrap, I mentioned the possibility of the Vikings either looking to trade or cut Greg Jennings now that they had made a trade to acquire Mike Wallace from the Dolphins. Saturday the Vikings officially released Jennings which leaves one to ponder (no pun intended) whether the Raiders could look to nab him.
The interest in Jennings could be two-fold. Jennings spent the first 7 years of his career in Green Bay, the firs six of which with Reggie McKenzie in the Packers' front office. McKenzie's final two season with the Packers in 2011, Jennings went Pro Bowls and over those six seasons Jennings averaged over 1000 yards and 8 touchdowns per season.
In 2013 Jennings joined the Vikings as a free agent. That first season he led the team in catches (68), receiving yards (804), and receiving touchdowns (4) with Bill Musgrave as the team's offensive coordinator. And he did it despite Adrian Peterson getting almost the entire offensive workload and some pretty terrible QB play between Christian Ponder and Matt Cassel.
Jennings is 31 years old and will turn 32 in September so he may not have much left. Even still his 742 receiving yards and 6 touchdowns last season would both have led the Raiders team.
As far as his willingness to join the Raiders, Jennings got his Super Bowl ring back in 2010 along with Charles Woodson on that same team, so he won't be as desperate to be one of those veteran players latching onto a team with a chance to finally lift the Lombardi Trophy before he retires.
You won't really find better options on the market at receiver with the top options long gone. There could be some mutual interest, so I could definitely see him coming to Oakland.
