Absolutely. Chanot and Callens is likely the best CB pairing in the MLS right now.
All I can do is pray to the omnipotent being in the sky and/or earth that neither get injured this season... otherwise we have a continental shelf in quality.
I think Brillant is ok, despite his gaffe last week. I disagree with Vieira that he can handle RCB in a 3-man backline though, or RB. He's an aerial and clearance guy, meh with the foot.
