People are honestly opposed to this idea?
I realize the Reed is aging, but he's still exponentially better (at safety) than anyone else we have on our roster (with the exception of McCourty).
He doesn't necessarily fill the need for an enforcing SS, but he plays rather physically and can play near the L.o.S.
Him and McCourty at safety would give us two rangy, instinctive, and athletic safeties who can make plays. It would allow us to play a very effective cover-2, and also disguise a lot of coverage. McCourty and Reed could also match up on TEs and WRs in a pinch.
If we were able to land Reed, re-sign Talib, and add CB depth via the draft, our secondary woes would be solved.
