The number of players whose careers have been derailed by injury is too long to list. For the Cleveland Browns, a few names always pop to mind starting with OL LeCharles Bentley. Bentley was a huge free-agent addition, returning to his hometown to help take the Browns over the hump.
Unfortunately for both the player and the team, Bentley never took a regular-season snap following signing his free-agent deal due to a knee injury and then a MRSA infection.
Recently, WR/KR/PR Jakeem Grant was supposed to be a huge addition for Cleveland’s special teams as well as a gadget player on offense.
