You won't believe how much money the Oakland Raiders paid Nate Allen

Former Eagles safety Nate Allen signed with the Oakland Raiders yesterday. The terms of the deal weren't disclosed at the time, but now they've been revealed per Aaron Wilson of The Baltimore Sun. You probably won't even believe they're real.

Nate Allen Raiders deal: 4-yr, $23M, $11.8M gtd, $4M bonus, salaries $2.9M, $4.9M, $5.85M, $4.85M, 2015 base full gtd

That's a lot of money! No ill will here against Nate Allen or anything, who is by all means a good guy, but that's just shocking.

Allen got a bigger deal than Rahim Moore, who signed with the Houston Texans, did at three years, $12 million, with $4.5 million got guaranteed. Moore was largely considered to be one of the best starting safeties on the market behind Devin McCourty, who ended up staying in New England with the Patriots.

Crazy. This is just a year after Allen tested the market and re-signed with the Eagles on a one-year deal worth $2 million (with another $1 million in play-time incentives).

How did Allen's 2014 performance really warrant what Oakland gave him? There's no way the Eagles even tried to match that.

...

And looking ahead, what is this going to do to the free agent safety market? Are the Eagles also going to have to overpay someone? I don't need to remind you that Philadelphia still needs a starter next to Malcolm Jenkins.
