Coming back from an injury is one true test of a player's natural ability.
As world-class athletes, NFL players can take a significant step backward from any kind of injury.
Along with the injury itself being unfortunate, the situation only worsens if that player never gets back to prime form. The flip side of that coin, though, is if the player does get back to full gear and really makes a statement.
Peyton Manning of the Denver Broncos is arguably the most notable example from 2011.
Upon returning, Manning shredded the Pittsburgh Steelers in Week 1, and despite a setback against the Atlanta Falcons, Week 3 was a solid performance as well.
Manning isn't the only one who came back from a season-ender last year.
That said, let's check out the progression of Manning and others since returning to the gridiron for 2012.
