When you are not the No. 1 or No. 2 wide receiver you have to do whatever it takes to make sure the team thinks you are valuable enough to keep around. If that means you have to return kicks--you return kicks and/or punts.
With just 24 receptions to his name last season Colts WR Griff Whalen is one of those guys.
If that means you have to get smacked like he did by the Jets Thursday night--than you get smacked.
