I think BMC have the right idea. Despite what happened in the Dauphine, Porte is probably more vulnerable to losing big time on the flat/rolling stages than he is in the mountains - especially with so many flattish stages. And, even if that's not the case, riders of the quality of TJVG, Dennis, Samu and Bookwalter wouldn't have saved him in the Dauphine and won't save him in the Tour if all the big leaders take turns on attacking Porte in the mountains. He will have to largely defend for himself there.
Now, on the flat though, BMC are probably the strongest GC team and can defend comfortably and even look to gain time there if the opportunity arises. They might as well play to their strengths rather than sending a load of relatively low quality climbing doms who would get dropped as soon as a super-domestique like Landa, Valverde or Fuglsang turns up the gas.
