He's kept himself wonderfully fit throughout his career, I do hope he can go on for another two seasons. I think they'll rest him for NZ if he continues and even South Africa might be too soon. Got to remember his avg has been lower these last two seasons than at any other time of his career - remarkable. 6 tests next summer against WI & Pakistan so there's wickets to be had.
but the thing is planning for the future tours and it starts from this winters, jimmy should do the right thing and step down before they drop him, lets somebody else have ago, he got nothing to prove to anyone, and his record at test cricket is the best for a fast bowler and only the best spinners have the edge on him, the rebuild for the future is a must and the ashes down under in less then 2 years time so, archer broad woakes stokes and another 2 or 3 bowlers from the up and coming like curran or wood must all come before jimmy
