Guys who should have been decent but weren't, or an XI of blokes who downright sucked? I might try my hand at the latter, but for England (naturally).
1. Darren Maddy
2. Jason Gallian
3. Ravi Bopara *
4. Kim Barnett
5. Mark Lathwell
6. David Capel
7. Warren Hegg +
8. Chris Schofield
9. Tony Pigott
10. Ian Salisbury
11. Tim Munton
The worst England XI that I have seen would not include Bopara (the hatred from hime here is laughable) but would certainly include Ronnie Irani. Mark Illott, Martin McCague and Min Patel would get gigs as well.
For an All Time England XI of could/should have played much more:
Charlie Barnett - but for the 2nd World War?
Andrew Sandham - would have been a regular in the 190s if Herbert Sutcliffe hadn't been there.
George Gunn - played some Test, should have played many more
G.F.Grace - his brother felt GF was the better player, a stretch but certainly would have played more but for hos untimely early death.
Ernest Tydesley - Neville Cardus considered him a better batsman than Patsy Hendren who played a lot of Tests
The Hon F.S.Jackson - a first choice over many years for home Ashes Tests but, for business reasons, never played against SA or toured Australia
Jack Richards - (OK personal call) a far better keeper and batsman than Paul Downton who played many Tests
F.R.Foster - fine all rounder who came to the fore shortly before WW1 and his life fell apart soon after
Martin Bicknell - made his debut in the 1993 Ashes and got tarred alongside some much worse players. May not have been first choice but would have been a fine player arounfd the team for a good while.
Neville Knox - very highly rated fast bowler who had a very short career due to injury
Charlie Parker - almost certainly the best SLA bowler in England during the 1920s but not liked by those in power
