Going forward in this era, it's a disaster to dress multiple one dimensional guys. I've said it before and I'll say it again, Sal and Volch both in the lineup tend to bring out the worst in each other. I think there's always a spot for one shutdown, pking, hard hitting, shot blocking defensemen on the roster. Likewise, there's always a spot for supreme blue line offensive talent who might have a lot of warts in their own end. More than one on either offensive or defensive really pushes it.
The idea is to have a good mix of both offensive D-men and defensive D-men. You need both. Daneyko was never an offensive guy, and Stevens became more of a defensive guy from '96 on who would occasionally pitch in. '
The problem with defensive defensemen is they tend to get noticed when they're not getting the job done, mostly because their positive contributions don't often lead to glamour numbers (goals and assists).
The rest of the four, you really want to see as many two way defenders as you can. Think Larsson, Greene, Fanye. Not necessarily guys that score, but guys who have somewhat of a clue as what they're doing if they join a rush. Fortunately, I think that's what a lot of us get excited about, with Merrill, Severson, and Gelinas coming up - they all seem to have that two way ability. Not to mention Sanaiti or whatever his name is. An offensive game remains to be seen, but it looks like he could be that shutdown guy for the next decade by all accounts.
