I don't want to say "I don't care about projected offense" but for someone to have a touted defensive + skating + effort game at 18, they probably have the work ethic to transcend whatever people assume their scoring upside is.
To draw an analogy ( a bad one, but hey), he reminds me a bit of Bo Mikael Andersson: great speed and other parts to his game. If they think De La Rose's offense can develop, great, he's got qualities they could use. And if not, that's ok too. There are a lot of guys to like.
