If Veleno turns into another Larkin I'll be thrilled. But I don't think a center group anchored by two guys like that would stand much of a chance against the top offensive centers in the league. I don't think they'd score enough, in enough different ways, to compete for a Cup. But it's nothing to turn your nose up at. I'd rather have two guys like that than just one. I mean, there ARE examples of teams that have won the Cup without elite offensive centers. Boston in 2011, St. Louis a couple years ago. But it's not like those were dominant teams that had staying power. Hardly the teams I'd be trying to emulate as a GM.
The ONLY team that was both dominant, and weak at center, was Chicago and they happened to have HoF level talent at defense (Keith) and on the wings (Kane and Hossa). So I suppose if we want to be weak down the middle we might wanna find some Hall of Fame level talent everywhere else, and pronto.
