KK was a bad draft pick. That was the issue. We've hung on to him this long because of that, not because of any merit.
He's a great skater but he doesn't have the brains to be a Dman. I think he'd be a good winger though.
I think that's true, but I also think it's true that we made mistakes with his development, and ran into some bad luck (two shoulder surgeries, or was it three, in addition to the one he'd already had). He definitely made steps forward before going to Syracuse, and we definitely handled him differently than other prospects, which I think, in hindsight, was a mistake. And he lost years on his development in that time. And maybe there's a point where you just can't get that lost time back.
That's not to say he was a good draft pick. He'd already had one shoulder surgery, if I remember correctly. So this was probably another case where Yzerman/Murray ignored red flags in search of a homerun. But, even so, I think we mishandled his development and made the problem worse, or, at least, made him less likely to reach whatever potential he had, and then there was a lot of bad luck along the way.
Koekkoek did, at times, show flashes that he could be a good player. They seemed to dry up in the last two years though. The Pens series in 2016 might be the best Koekkoek we'll ever see, sadly. That said, he could still develop into Coburn's replacement on the cheap.
