Never played in a cap league so I can't speak to that, but I'm a Sens fan. I'd avoid Colin White completely, he's definitely not a 1C, and shouldn't be a 2C either, unless you're the Ottawa Senators with no real center talent available immediately. But even with that, we have a couple young prospects in Norris, Brown and probably Stutzle that will definitely be ahead of him, so he won't be our 2C either going forward. He's not a great player in general to be honest, and his contract is horrible for us, so if that's a consideration for your fantasy league, it's just one more reason to pass up on him. He's better served as a winger, but even then he belongs on third line not second. We may not even protect him in the expansion draft, he's that bad unfortunately, most of us are hoping he gets swapped out for picks soon before his value plummets completely and the rest of the league figures out how bad he is..
Edit: I should also mention he's been a healthy scratched a few games already this season, rookies and other scrubs including 4th liners have been chosen to play over him, which is not a great sign regarding his progress at this point. Some of it can be attributed to questionable roster decisions by our coach, but most of it has to do with White himself.
