The problem isn't about the players, for the most part. Sure, they could use one or two good SAH Dmen, but so could most teams. Maybe one or two big, nasty, middle six forwards. At some point, though, someone has to wonder at the success of ROR, Reinhart, Eichel, and to a lesser extent, Mittelstadt and Erod(I am leaving out a few others)once they leave the organization.
Problem is coaching, and team construction. They are not consistent, and have no identity, besides being losers. Are they a great offensive team? Tough? Defensive? Heavy forecheckers? Conservative? Answer is that they are all of those things- sometimes. Other times they are none of the above.
Bringing in a couple of players with good talent and huge work ethic would help, sure, but would be futile if the management didn't back them up. I don't think they know how.
