High teens is a bit of a stretch. I have Cowan as an offensive 3rd liner with potential to be a 2nd liner winger. Don't think the play is dynamic enough for PP1, but PP2 for sure...I had him as Hyman-lite last year before Hyman went supernova. Average year: 40pt floor as third liner, 60pts if he hits with 70pt career year. Comparable players (points wise, not style/size wise) I have range from Daze to Hoffman to Mangiapane with some third liners mixed in. The outlier comparison is Mark Recchi, which would be nice, but there's about ten 45-60 pt guys for the one Recchi, and a lot of luck is needed for that to happen. So...60% third liner, 30% second liner, 10% star.
Anyway, given the list, I wouldn't have him above Yurov or Guenther (30/31) who are both playing and excelling against men, maybe Snuggerud or McrGroarty, in the mid-30's, but their ceilings could be 1st liners. Definitely ahead of MBN at 39, around the Kulich area is where I'd have him. So 8 higher...splitting hairs at that point. Mind you, the two guys around him (Nadeau and Ritchie) I have higher as well, so I'll chalk that up to Wheeler-isms.
