Trade up for Parsons?

In Todd McShay's most recent mock he has Micah Parsons going 15 to the Patriots.
I'd trade 1st &3rd this year and a 1st next year for Parsons. Our defense was great when Alexander wasn't injured. I believe Parsons would put us in the playoffs, regardless who is playing QB.
Thoughts?
There are a handful of really good coverage LBs in this draft that will probably still be available at 60. If the Saints didnt have Davis and needed that role to be filled, I might be tempted to go after Parsons. As it stands, I'm not willing to give up draft picks for any reason right now.
