If you watched the Thursday night game between Pittsburgh, and Baltimore, you are probably familiar with this incident.
It occurred while Jacoby Jones was returning a punt, and Tomlin is seen clearly over the white line, looking over his shoulder, and grins afterwards. The league is currently looking into it. So what does everyone else think about this? No big deal, or downright dirty?
Regardless, it's a bad look for the NFL, and a head coach like Tomlin should know better.
