I've probably written as much as anyone about how Gardner has been screwed at every stop and underestimated. Jacksonville was a shitshow. He outplayed Foles, who had a big deal, and the other journeyman they had at the time, despite that club being an even bigger shitshow than the Raiders. He also didn't get a great shot in Indy since they wanted to go to Richardson. Similar situation. And now the Vegas situation is bullshit again. Similar to Jacksonville but with an idiotic, unstable head coach who had a run with the other guy (O'Connell) as the interim, and where he yet again has a shitty OL and general lack of weapons on offense other than a good rookie tight end.
All that said ... he had a pretty decent shot when Hurts was out in Philly and, as I recall, shit the bed. It was unfortunate, since especially at that time, I thought he could demonstrate he was a legit mid-grade starter who could win in the NFL with some actual talent around him.
So it's a mixed picture to a slight extent. He constantly has been screwed, and he has done a lot better in some shitty situations than others have, but while he's a guy I'll always root for, it sucked not seeing him grab the one limited opportunity he had with a decent situation.
