Well he's over emotional and immature, collapsing to the ground when Denver got the td & 2 point conversion was, well, like a little kid. But maybe that's just how he always will be, and he still had a hella season and got that far to do it.
Marshawn's press interactions were always bizarre, and kind of childish too.
To me the key thing was how he congratulated Peyton. An over emotional, immature QB for another team doesn't hurt my feelings any. I came to have fun watching the big goof, and I sort of felt bad along with him too. Oh well. On to 2016.
