Actual thoughts and not just me being snarky like the above post:
I don't hate this. As much as I would've been interested in seeing him on the Barracuda (I have tickets for their games here next weekend), I worry about how that coaching staff doesn't have the best track record of developing dynamic skill prospects. And while it was fun watching him deliver a couple of "oooh. ahhhh." highlights in most games, I think there comes a point where the lack of production becomes as much of a mental detriment to him as it does a failure to develop physical skills.
Will playing in the SHL help him with playing on and reacting to things on a smaller NHL rink. No. But is that really his issue? I'd argue so far that rink awareness and operating in the confined space has not been a problem. What it will do is give him a chance to go into an environment where he'll be a top guy who's relied on by the team, which will then force feed him important minutes and heavy expectations of production. And it will likely come with a working agreement with the club and its staff to help focus on Eklund getting bigger/stronger to handle the physical rigors of the NHL game while encouraging him to develop his shot and aggressiveness in order to make him a more dangerous scorer at the NHL level.
It's no an ideal solution, but I don't honestly know what the ideal solution is. Big man on the Cuda is no guarantee given that I can't even think of the last guy who played significant Cuda/WorSharks development time on his way to NHL eliteness (Cooch? He was only there for like half a season. Pavelski was 16 games. The list of high-impact players who played for a Sharks farm team is basically empty unless you set the threshold down at like 45 games or fewer). Staying in San Jose is asking him to produce a "disappointing" season while burning a year on his contract for no real significant benefit. Sending him to Sweden is putting him in an inferior league with a different setup to North American hockey. It might just be that being in Sweden is the best of a bad set of options.
