Cav needs to step it up this year, he's been usurped and as I see it he has three possibilities:
1) Get back the sprint crowd. I still think he's capable of beating Kittel, but Omega need to be willing to lose the race and force Giant to do some work this year, or they'll just get swapped every race.
2) Focus his talents elsewhere. The guy can TT well, he can last a distance and he can obviously sprint. I'm not saying he's going to start winning Paris-Roubaix, but he could start competing some less sprint friendly one-day races. He's not got Rio in his programme anymore, so why not give it a go if Kittel is just too fast?
3) S£&^, small races.
