On one hand, I agree. A net front guy is a lesser requirement.
However, I really think that by getting a guy like Rasmussen who can take that role and look to be defensively responsible as well, you let Mantha, Svech, and others develop into the playmakers and the guys who go get the puck and hang onto the puck. You're no longer tempted to waste a Mantha on net front duties because he's 6'5", you're able to let him roam around and do more of what he did in juniors offensively when he filled the score sheet up like crazy.
I'm not saying that the Wings necessarily did right by drafting Rasmussen over the other choices, but it isn't some "holy crap, they made a huge, obvious mistake, either"
