As I sorted through the 136 signings that have happened in the NFL, one signing in particular stood out to me almost instantly and never left my mind—the Baltimore Ravens signing former Arizona Cardinals safety Tony Jefferson to a four year, $34 million deal with $19 million being guaranteed.

This is the best signing of the offseason.

Jefferson has it all—he's only 25-years-old, he is a physical, effective tackler, he can stop the run, he can contain plays from exploding and when asked to, can do his due diligence in rushing the passer.

It also cannot go without saying that Jefferson was PFF's sixth best safety in 2016.

If Jefferson needed anything to improve upon, it would probably be in the coverage department where he allowed 24 receptions on 44 targets his way, but he also ranked 39th in pass coverage snaps, so it's hard to say how that statistic would have ended up if he he played more in that department.

With the Ravens, Jefferson might have more of an opportunity to play in coverage as he pairs up with fellow safety Eric Weddle—perhaps the best safety duo in the NFL.

With Jefferson in coverage, this will allow Weddle to use his immeasurable football IQ, patrol the field and make plays—he doesn't appear to be slowing down.

Jefferson's signing allows for so much more flexibility in defensive game planning for Ravens defensive coordinator Dean Pees.

The Ravens got an excellent deal with Jefferson, Jefferson finally got paid (and accepted less money) after starting his career as an undrafted free agent (he talks to Andy Benoit of MMQB about it here) and the move makes the Ravens secondary one of best in the business when you take Weddle, Jefferson and cornerbacks Jimmy Smith and Tavon Young into account.

And oh wait, the Ravens general manager Ozzie Newsome has said the team isn't done yet—maybe add cornerback Morris Claiborne?
