Doug Whaley has made it clear the Buffalo Bills' top priority in the 2016 offseason is to keep the left side of his team's offensive line together.
The price to make sure tackle Cordy Glenn and guard Richie Incognito don't go anywhere, though, will be high.
In separate rankings of the top 20 available pending unrestricted free agents by nfl.com and analytics website Pro Football Focus in the past week, Glenn shows up on both lists and Incognito is on one.
Gregg Rosenthal of nfl.com ranks Glenn as the fifth-best pending free agent.
"True franchise left tackles are awfully hard to find," Rosenthal writes about Glenn. "That's why he's a strong candidate for the franchise tag."
That may be a bit of a stretch. Last season, the cost of the franchise tag for offensive lineman was $12.943 million. That number can be expected to rise for the coming season – and could be more than the Bills are willing to spend. A long-term contract with a lower cap hit would be more preferable.
PFF, meanwhile, ranks Incognito as the No. 6 available pending free agent.
"Incognito’s off-field reputation preceded him heading into 2015, but he has always been one of the better guards in the league, and his signing always seemed a shrewd piece of business by Rex Ryan from an on-field perspective," PFF's David Aitken writes. "It would appear the year out of the league did him a world of good, as he never had a season as strong as 2015 with Buffalo. Baltimore’s Marshal Yanda held the top spot in PFF’s guard grades for the second straight year, but right behind him was Richie Incognito, buoyed by an excellent performance in the run game."
Glenn is No. 20 on PFF's list.
"The Bills’ offensive line, as a whole, had a huge turnaround from the largely disastrous performance of the 2014 season, but it’s a testament to Glenn’s consistency that he was the highest-graded Bills offensive player in 2014, despite the poor play of his fellow linemen," Aitken writes. "Having been in the top-15 in pass-blocking efficiency each of the last three seasons, and starting every game, Glenn stands to see a large pay increase as the market’s top pure left tackle."
