Froome is an unknown quantity in one-day racing but some of his moves in the Tour show that he could be worth an each-way bet.
A lot has been said about Cummings and his uncanny knack of winning stages in big races, but there's a big difference between being allowed to go in a break on a stage where the GC contenders aren't threatened and making a solo attack in a one-day race where everyone is after the same prize.
For me, Stannard is the best prospect after what he did at Paris-Roubaix this year, although conditions in Rio will be very different.
Yates could be in with a chance as long as the flamme rouge stays intact.
Thomas will work his arse off for the team but I doubt he'll win it himself.
Actually, I don't think Britain will get a medal in the road race. For me, the ones to watch are Nibali, Van Avermaet and Valverde. Froome has a good chance in the TT though.
No idea about Cav's chances in the Omnium - I have no idea who he is up against.
