Cav to Sky ?

Bad move if you ask me, Sky was set up with the intention of producing a british winner of the tour de france within 5 years, if they take Cav on then how do they race the tour. Basically they build a team around Cav and have him supported by say thomas, Swift, Cummings, an other. Can you see Boasen Hagen playing second fiddle to Cav because i cant, so it gives us us Cav, Swift, Thomas, Cummings, Boasen Hagen, an other.
We then have GC man Wiggins to come in, leaving 2 slots left which i assume would go th Uran and Xandio or another mountain specialist.
We now have to ask ourselves does Brailsford think he cant produce a british winner in the remaining 3 years of his prediction and does he just go for stage wins to keep the sponsors happy, if so then i cant see Sky continuing with sponsoring a team who wont deliver on their initial remit..
The tour has proved that to win it you need 8 riders fully commited to a team leader, as BMC were this year unlike Leopard Trek who split their eggs in 2 baskets and suffered as a result.
Cav should go to a team fully committed to him without a GC Contender, Astana or Cofidis come to mind, or even stay at HTC. Either way a move to Sky would be bad for all concerned.
