I don't see any reason necessarily why Bell shouldn't be selected if the situation calls for it. There are plenty of players who've struggled in international cricket in their early years, spent ages in first class cricket, and then returned to be highly competent players, Matthew Hayden being an obvious example. Not necessarily saying that Bell would succeed, but if he's stopped mucking around with his technique, and our opening problems continue, I see no reason why he should't be given another shot. His form has been excellent for the last couple of seasons and he's been playing plenty of fast scoring, exciting innings. He's also looking likely to break Papps' run scoring record from last season. With a minimum of 4 (and probably 5 considering how well Wellington are doing in the comp this season) games remaining this season, you'd have to back him to the score the less than 300 he needs. Still, Papps and (especially) Cumming deserve a game or two more yet, and after them, Jamie How is probably the next cab off the rank, so I'd be somewhat surprised if we saw Bell in a Black Cap this season.
