Ryan Wendell, who has started 32 straight games at center and is only 27-years-old, has also not been approached about a new contract, although unlike Mankins, he is without a contract altogether and is an impending free agent. It's obvious Wendell isn't a top priority for the Patriots, who discontinued talks with the center midway through the 2013 season.
Mankins is the priority obviously, but the Patriots shouldn't overlook Wendell. He is not an All-Pro center and chances are he won't become one, but he is serviceable and reliable. In 2012 he played 1,379 snaps, the most of any player in the NFL. @joeloobs @patriotslife
