Stats time. Key averaged 14 for Kent in the FP Trophy, 28 in the T20 cup and made just 4 in his only Pro40 game of the season. Not convinced he'd be a good ODi pick tbh.
Bell's actually had a very, very good season, and happens to have a better ODi record than everyone in the current England side apart from Denly. He's really not that bad an ODi player. He's averaging over 80 in List A cricket for Warwickshire with 2 hundreds and 4 fifties. Collingwood would be a far better candidate to be a member of the 3 muppets.
Jonathan Trott, Ed Joyce, Steven Davies, Ian Bell, Michael Lumb and Paul Horton would all be far better options than Rob Key. The young Notts lad, Alex Hales would also be better than Key.
