I'm honestly wondering if there's something going on in Riq's personal life that has him bummed out in general. Or maybe he just isn't digging living in and/or playing for the (Mike Mac coached) Seahawks. Whatever it is, he just simply doesn't seem to be the same happy go lucky, jovial, lighthearted cat that he was last season.
Whatever it is, be it personal or otherwise, I really hope that he figures it out, for HIS sake, cuz I genuinely like the young man. Depression is real. And the outward effects manifest in a myriad of ways.
ETA: In case it's not obvious, I'm totally spitballing, here. I don't know anything about him on a personal level beyond what he displays in the media.
