Mixon confidence?

[WestCoastBengalsFan]

I don't know about you guys but Mixon looked it wasn't that interested to be playing today. I don't know what's going on with him but he was not lowering the boom and trying to "truck" anyone during contact, pretty much looked like he was either uninterested or maybe he had some kind of injury? Not sure what is going on but I've never seen him play with less enthusiasm, was it just me or did anyone else see this? I've been wrong before...
