Everyone has a different definition of elite. With mine, I'm not sure I'd consider him an elite QB, at least not yet. What he is, is a guy that won't be outworked. He's tough as hell. He's a player that has come a long way in a short amount of time (which bodes well for his future still). As mentioned earlier, he's a good dude too. And I do think he is the perfect fit for that Eagles offense. Not to say he wouldn't succeed elsewhere, but he's in a great spot right now. This was close to being his 2nd Super Bowl title... and he sure didn't cost them the first one by any means. I'd guess he will probably get another shot too... and he's not a guy I'd bet against in that situation if so.
If his arc continues, I could see him ending up as a better Russell WIlson. Which elite or not, however you want to stamp it, puts him in Canton at the end of his career.
