WR Divas

What is it about #1 WRs who become divas? Now Michael Thomas not only got into a fight, but apparently he's been exhibiting erratic diva-ish behavior for some time. Sure there are players at every position now and then who have character concerns. But why do wide receivers seem to have an inordinant number of jerks. I guess we should be thankful we have high character guys on our team in Evans and Godwin, although that's how you are supposed to act. We shouldn't have to thank our lucky stars that our guys act like normal human beings, but that's the state of affairs at that position.
