Danny D would most definitely be a depth signing for this season, getting a few games in and maybe, MAYBE a couple of playoff games....next season though, with what looks like White headed out, even if Kindl re-signs there will be a spot for him because even if Colaiacovo doesn't get waived, he would get hurt and that would allow Danny a spot on the roster. Honestly there is no one else in GR ready to come up, as good as most of our D prospects are, they are all still at their junior clubs or college. Danny is 23 years old tomorrow and is ready to step in to an NHL spot. I hope it's with Detroit.... He can rotate with the ever present #7/#6 Kindl... Besides in two years, depending on what we are paying Howard/Brunner/Filppula/Smith/Andersson/Nyquist and Kindl, we have to re-sign Ericsson, Quincey (probably) and Dastyuk, not to mention players like Sheahan an Ferraro who would likely see some time up here now and then, having a nice EL contract with Dekeyser would provide some much needed cap relief in 2014...
I agree that Dekeyser could step in this year, and could next year as well, I just think its extremely unlikely given how the Wings handle prospects.
We have 9 defenceman as it is. Kronwall, Ericsson, Quincey, Smith, and Lashoff are all essentially guaranteed their roster spots going forward. Kindl, Huskins, White and Colaiacovo are all battling for the last spot.
Its possible White gets traded but there's a good chance that's as part of a package for another defenceman. The only way Dekeyser would see any time on the Wings this season is due to injury, and even next year I'd imagine the best Dekeyser could hope for is to battle for the #6 spot in camp.
If he lost that battle there is no way they'd waste him in the pressbox as the 7th defenceman, he'd be getting big minutes in Grand Rapids with his former coach.
