Breer points out that Mankins and his agent were indeed looking for a deal that was at least the same as Saints guard Jahri Evans, who signed a seven-year, $56.7 million offer with an average annual value of $8.1 million per year earlier this offseason. Evans, like Mankins, was a restricted free agent coming off his second Pro Bowl.
Breer reported via Twitter that the Patriots offered about $7 million per year on a long-term deal to Mankins, which apparently wasn't enough to get an extension done.
The 28-year old originally signed a rookie contract which was for five years and $6.4 million, with $4 million guaranteed. He was assigned the first and third-round tender – the richest possible option for a player – back on March 4th of this year.
The one year tender doesn't mean it's completley over as there's still time to iron out a new deal on an extension. Unfortunately for now there appears to be some serious work to do before the two sides could even have a shot at working something out.
