Yes on the Samit Patel issue, he really has portrayed a lack of appetite (for once) to get fit. Anyone that shows such a lack of dedication in attaining certain fitness targets that have clearly been set for them do not, imo, warrant a place in the side. Not just because of the fitness issue, although that is a big factor, but it just says to me that if things were getting tough in the middle, they would invariably take the easy option out of there, and not be willing to work hard and do the ugly yards for the team.
Back to the thread heading, personally before the W/C started I was in favour of Trott opening, and while I don't think a promotion to open would upset his current rhythm, it may be seen as a risk not worth taking. Therefore for me it has to Bell, if the opposition open with spin he's very adept at countering that, plus with pace on the ball he has all the tools to expose the fielding restrictions in his own perfectly orthodox fashion.
All options are worth considering, but I would quickly discard ideas such as Swann and Broad. The best time to bat is against the new ball in the sub-continent, and one of our more accomplished performers deserve the opportunity to get us off to a good start. Prior and Bopara would be looked to to give the side a bit of a kickstart, but I feel they are more effective in the middle order, personally.
