I guess it depends on your definition, but I think this team has four bottom-six forwards based on a (loose) comparison to Martin: Glendening, Miller, Sheahan and Athanasiou. Obviously, the latter two have more skill. If anything, I think the Red Wings have too many fringe NHL forwards. Guys who basically walk that line between "complimentary offensive winger who needs to play with superior talent" and "AHL-caliber talent".
I would have taken Martin over Miller as well, but part of the problem with this team (and Blashill has admitted it) is that too many guys were unsure about their roles last season. You need a player to know what his role is on the team and commit to it. For example, Jurco is a guy on the fourth-line who thinks he should be in an offensive role (I'm not trying to pick on him, I just think he's the best example on this team). If your bottom-six/fourth-line guys know who they are, so do the guys above them. The line combinations and TOI were a mess last year, and I think clearly-defined roles would help to fix that up. Part of that means Blashill needs to stop his love affair with Glendening (why does it change L.G.D. to disney.com?) and commit to playing the skilled players more often.
