I may get flamed for this, but whatever...
Danault is a BETTER center than Drouin. Not saying he is a better player offensively, but there's no doubt in my mind he's more worthy of the #1C position on our team (sad to say as it is). Drouin is the #1C by circumstance, plain and simple. We gave up our top prospect for a guy expected, not projected, to play as the top center.
Obviously, I don't want Danault as our #1, but he's a lot better than Drouin is at the position.
I also believe Kotkaniemi is going to be a better center than Drouin. He has more of the tools expected from a center, especially a two-way one. I personally think he can reach 1C status, but even if he ends up a quality 3C, he's still likely to be a better center than Drouin.
I think Drouin is incredibly gifted offensively and I was one of those who really wanted him when he was going through all that crap in Tampa. However, I'd like to see him be more free offensively as a winger so that he can do what he does best which is to create offense.
