Quoting: HabsIsland
There are teams have multiple 1line centres. For example Washington has Backstrom and Kuzy. Boston had Bergeron and krejci. PITTSBURGH has Crosby and Malkin etc. There are also teams that have a 1c and 2 2nd line centres. For example Carolina with aho,necas,staal,trocheck. FLORIDA with Barkov, Bennet,Verhage,Reinhart.
Proof that there is more than 32 line 1 centres . And surely more that 32 of 2nd line centres. Which means Dvorak is a 2nd line caliber player.
There are some names on here that don't play center (Verhaeghe, Necas) and some that aren't 2C's (Staal) lol. You're right there are some teams that are lucky to have two 1C's on their team. Put it this way if the NHL did an entire re-draft position by position. Not taking contract into account and just talent, is Dvoark one of the first 64 center selected? For me the answer is no. I put Dvoark in that same range as Charlie Coyle and that's a great 3C on a cup contender.
If you want to call Dvorak a "2nd line caliber player" then great you're welcome to your own opinion. As I've said he's a 3C on a contender and a 2C on a bad team, but if he's your 2C then odds are you're team is very deep talent wise and you're not going very far. Kind of funny the two teams with the least amount of points and the worst P% so far in the NHL this year are the two teams that Dvoark was the "2C" for.
BTW looking at some of those teams you mentioned...
WSH - 1st in the NHL
CAR - 2nd in the NHL
FLA - 4th in the NHL
^Those team are (GASP) all contenders!
PIT has been without Malkin all year and Crosby has missed time as well. Up until this 8 game win streak they had they were barley at .500
BOS saw Krejci leave to return home, needed Coyle to play to 2C and wouldn't you know it they've struggled and are battling just to get a wild card spot.
