I feel obligated to jump into the Stanley discussion just cuz everyone is doing it. The above seems about right, minus, to a degree, the Garrett article. I'm not sure the article contributes that much to the issue, it's a long time ago. I'm sure I read it, but I certainly don't recall it. If Garret panned the pick, he's hardly alone especially outside of Winnipeg and its fans.
That said, Stanley is an NHL defenseman. A bottom pairing, 6-7, if you will. Every team has those, we've traded or picked up numerous off waivers over the years. We've also cut bait with many of them over that time (the Chisolm part of the post above I deleted is a great example).
The Jets traded up to draft Stanley in the first round based on size, seemingly in hopes of him turning into the next Chara (someone should explain probability to the scouting crew). The Jets subsequently have given a guy who is 6'7" so much rope you could run it lengthwise from here to Calgary while not giving it to other players that may well be better (cough*Kovacevic*cough). Opportunity after opportunity has been granted him while others haven't seen the same generosity. We're nearly 9 years into this experiment and Stanley is what he is.
I think the frustration is more from how much effort has gone into a talent that was very unlikely to meet expectations than anything else (his skating and mobility have always been subpar, one of the key factors in rating prospects - to this day his agility reminds me of mine). If, as you say, he was 6'2 I'm guessing he would have been traded/waived years ago. Retaining and providing so much opportunity to what is a easily replaceable asset likely drives all the angst.
Now I feel part of the group.
