I'd say Washington. That wordmark logo is absolutely fucking horrendous. Give me either the screaming eagle unis from Ovi's rookie year, or even bring back the Weagle, but with the colour scheme from the 2005-06 sweaters.
I'm a Capitals fan and I completely agree. They switched to the current look the same season I became a fan, although it's been all I've known I think it's the worst logo in the league by some distance.
