Sometimes, it's worth going back in time and revisiting what once was to determine whether it can happen again. And it's worth remembering that, less than two years ago, Jimmy Graham was considered one of the all-time great tight ends.

But headed into the 2015 season, there were significant doubts about Graham's fit in the Seattle Seahawks' offense. Graham was moving from the New Orleans Saints -- the team with the fifth highest pass-to-run ratio in the NFL in 2014 -- to the Seahawks, who sported the second-lowest pass-to-run ratio that season.

These concerns weren't without merit. Graham averaged 6.7 targets per game in the 12 games he played in 2015, far short of his 8.7 targets per game average from 2011 to 2014 in New Orleans. And he achieved only one 100-yard receiving game in 2015, a feat he accomplished 13 times from 2011 to 2014.

And then in Week 12, Graham tore his patellar tendon, the injury which NFL players find the most difficulty returning from post-surgery. So no one was really banking on Graham being a force ever again, let alone in 2016.

But in the past two weeks, Graham has been on a mission to prove the doubters wrong. And with two straight 100-plus-yard receiving games under his belt, he is rounding back into form.

He's been more efficient than he ever has been, registering a 0.90 Reception Russell Wilson developing in a way that never seemed to take off in 2015, the buy-low window for Graham has closed.
