Dame fan's inside source turned out to be, I'm about 98% sure, Duval Kamara. As TerryTate said, he's a big-time rah rah guy, and ever year he posts about how unbelievable the team looks in the off-season and how the team has never worked harder and the team's chemistry was at an all-time high and yada yada yada. And then we suck. And he ALWAYS said the player that was going to surprise everyone was Duval Kamara, and he always, well, you know his story. (I mean, he ALWAYS talked about Kamara.)
I personally liked reading his stuff (always FULL of exclamation marks as TT stated), because it was the offseason and who cares if the guy got excited and drunk off the Kool-aid. But I got to the point where I never believed a word he said. And, as was stated, he would disappear when things slipped, which it did all the time under Weis. I'm of the state of mind that if you talk the talk, then show up good or bad, Damefan doesn't. In fact, I haven't seen him on ISD in over a year.
