The likes of Andy Fenn and Adam Blythe have shown that even with Sky around young Brits can, and will get WT rides with teams other than Sky.
Also, riders like Scott Thwaites and Erick Rowsell getting good races at Endura before hopefully stepping up.
Plenty of places for young Brits to ride, and get good races, other than Sky.
But, if they're successful, then the chances are Sky will be there to grab them back. Dowsett went to Trek-Livestrong because he'd get a better calendar than the domestic one, but as soon as any promise, back into the Sky umbrella he goes. And I have to say, Ian Stannard probably got more from his year at Landbouwkrediet and year at ISD than he could ever have got either on the domestic calendar, or as a totally untested neo-pro at Sky (unless, like with Kennaugh, they have high expectations of him).
How many Britons are there at the top 2 levels outside of Team Sky?
Bellis (now likely without a contract, severely injured of course)
Blythe (took the gamble of relocating to Belgium as an amateur)
Hammond (long pre-dates the Sky movement for cycling)
Lloyd (journeyman, probably not long for the top 2 ranks anymore, pre-dates the Sky movement)
Millar (pre-dates the Sky movement)
Wegelius (long persona non grata with British Cycling, retiring now anyway).
That's actually more than I expected. But the acid test will be, how many will there be in a couple of years' time, once the journeymen and elder riders like Lloyd and Hammond are gone - Sky have been keen to take pretty much every successful Brit from wherever they are (Wiggins, Swift).
I like the sound of Endura stepping up, however. I think that will be good for British cycling, because it will give an alternative route to the top that doesn't require such a leap of faith as that which had to be taken by the likes of Blythe, Faiers and Metcalfe.
