I shouldn't be surprised by this.
I'm not surprised by this.

at people who were targeting him in drafts.
I didn't understand it either. There have been nothing but major red flags surrounding Walker since early last season. When the Broncos would rather go with Darrell Jackson and Keary Colbert, that speaks volumes about how little value the guy has in my opinion.
Value? What's wrong with you people. I'm sick of defending injured players but you keep condemning them down for being hurt like it's their fault. Al Davis was stupid but that isn't Walker's fault either. Blame Davis for overspending not hurt players.
Who's blaming Walker? I'm talking about the fantasy owners who were chasing Walker in drafts so far this year and believed he was a value pick. I never thought he was due to the large number of (in my opinion) major red flags that have surrounded him since his injury last season. I wanted nothing to do with him and now we have a very strong sign that his heart isn't in the game anymore. Now if you want to debate how good Walker was and whether he lived up to his first-round billing that's an entirely different subject. Frankly, I think the guy's career has been a major disappointment. Two great seasons is all he's had - one with Green Bay and one with Denver. That's hardly the type of stuff that was expected of him when the Packers made him a first-round pick. Ted Thompson is taking a lot of heat (in my opinion deserved) for the Favre matter but I always supported his position on Walker and there's no question he made the right call in not caving to Walker's demands for a new contract and subsequently getting rid of him.
PF, I love your enthusiasm that always is there when you post...BUT...Walker did live up to his 1st round billing unlike so many 1st round busts at WR in his league. He posted stats that probably 70% of 1st round WR never hit in their career. I am not a Walker fan, not a Walker supporter in any way however we do need to acknowledge that the guy flashed skills.
No question he flashed skills. It was easy to see why he was a first-round pick watching when you saw his talent. However, I don't think two standout seasons in six is what was expected of a first-round pick. Were the injuries a factor? Absolutely. But the bottom line is he was a first-round pick and most teams expect more out of that player than two good seasons in your career. Like I said, I always supported Thompson's stance when it came to Walker. He was 100% on the money in wanting Walker to prove he could play at a high level for longer than he did rather than just giving him the money after one standout season. As far as Walker the person, I've heard from people close to the Packers that he's a good guy but he isn't very bright. His low Wunderlic score would attest to that. He also is led by the nose by people who, at least in the Packers' view, didn't always have his best interests in heart. This could be because he isn't/wasn't bright enough to make the decisions he needed to make himself.
