A long qualification period into his 20's, a Test series debut against Ambrose, Patterson, Walsh and Marshall and the pre central contract era and the constant threat of getting dropped easily didn't help Hick.He's more of a white ball player really. I wouldn't expect him to achieve it. Graeme Hick managed to do it because of his 405 against Somerset that May.
I saw him play in a match at Northampton around that time. He was still qualifying. One of the best batsman I've seen. Just seemed to shrivel up in an England shirt.
Banton only needs another 61 to pass Hick's score of 405 though and his strike rate of 90.28 is nuts. With another 6 games to come, good weather and a bit of luck etc - I wouldn't discount it just yet.
