Since when has playing for Yorkshire been a barrier to playing for England?
A barrier to playing for England? Well, the perception of many is that its certainly a hurdle to overcome and that a talented young Yorkshire lad runs the risk of being passed over for a not quite as talented lad playing for one of the South Eastern/London clubs, Nottinghamshire or for Ashley Giles own side.
Is that a fact rather than perception? Hard to tell, but there is considerable evidence to support the concern.
Lets look at Rashid as an example. As of today, his first class record shows 280 wickets at 35 and a batting average of 34, including four centuries, all in pressure situations, and he has been the highest wicket taker amongst English spinners in three of the last four seasons. When representing England, he's performed well - winning a game against Australia with the bat and doing admirably well with the ball as well (with the exception of one day day at altitude in South Africa).
Accepted, Swann is definitely our number one spinner but the other three under sonsideration don't match up to these figures very well at all - Samit Patel has a better batting average at 40 , but has taken less than half the wickets in nearly twice the time and at an inferior average. Oh, and he's unwilling to meet even minimal fitness standards (in that, as of this week I, a 35 year old with serious knee problems and no history of watching my weight, can outperform him on the bleep test). Then there's James Tredwell, with an equivalent bowling average mostly accrued in Division 2, nothing like the strike rate and a batting average fully ten runs a knock lower.
All this would lead me to suspect that the selectors either know very little about what they're doing, or have some inherent bias, yes.
You can go further though - how do Stuart Meaker and Jade Dernach keep getting selected yet someone like Ajmal Shahzad comes in, performs well under pressure than gets shunted aside? Ah hold on, there could be something in that Saffer theory....
