Father Time looks to be creeping up on Charles Tillman fairly quickly. He seems to be about a step slow and very vulnerable on the field.
Tillman was seen stumbling on the field against the Seahawks trying to slow down Doug Baldwin. It's not a good sign when Tillman struggles to keep on with an average at best receiver.
It is still preseason so it's very possible Tillman hasn't turned the switch to full speed yet. Still, there's a lot of miles on that body and he did leave Lovie Smith and Tampa Bay without a deal, which is very telling.
At some point, the magic has to stop for Tillman. Age is still undefeated in the NFL and Tillman might be able to prolong the inevitable but it seems to be coming sooner rather than later.
The Bears have to face Calvin Johnson, Jordy Nelson and Corderalle Patterson twice a year. Tillman might be rotated out as the season progresses in favor of rookie Kyle Fuller once he's healthy.
