I'll have a bash; got a whopping 4/11 looking ahead from 2005 to 2008 (not strictly 2008 yet I know, but, well, close enough) so see how this goes.
Cook looks a no-brainer, but I would said Strauss looked nalied on in 2005 (in fact I did), but has to be a racing fav nonetheless. Young Joe Denly down at Kent has been putting some decent figures on the board, so I'll give him the other opener's slot despite never actually having seen him play.
Bell & KP have possession and (relative) youth on their sides, so that's 3 & 4 sorted; will stick with Colly at 5 too as he's still a newcomer to tests and is a fearsomely fit bloke. He's my captain too as he's probably the next cab off the rank when MPV's knee gives up the ghost.
6 is harder, the pessimist in me thinks Fred might be finished by 2008 (
) so Bopara is a far guess. Hildreth might come into consideration at somepoint too, but Bopara has his medium pacers in his favour.
Keeper: god knows. Throw a dart. Ambrose is possibly the best bat of the candidates, so I'll plump for him.
Bowlers: Broad, certainly. Has a natural, easily repeatable action and his height and batting are big ticks too. Hoggard I think will still be there; he'll only be 34 and pace has never been his primary weapon. Sidebottom might also still be in the shake-up, given his late start to tests (debut aside), but Anderson is younger and might finally become the bowler he's threatened to be so I'll back him. I'll give Monty the nod as our spin option, but suspect rashid will have debuted (and maybe disgarded after a bit of a pasting v India or Oz) by then.
So:
Cook
Denly
Bell
Pietersen
Collingwood*
Bopara
Ambrose+
Broad
Hoggard
Anderson
