I have noticed though that quite possibly Rashid's run up doesn't give him the consistency we are asking for, Warnes was a slow walk to the crease and a quick gather, rashid's is quick and maybe he get's a bit over excited and slows himself down on occasion coming to the crease which can put him off rhythm? Just a theory... as im no coach, but there isn't a coach in the england set up to tell him any different so all he can go by is his fellow batsman's words and his own personal feel
Warne was a freak of nature with enough strength in his shoulder to get away with a leisurely stroll to the crease. Most mere mortals trying to do the same thing would just bowl slow, loopy deliveries which would do the job at club level but get clobbered all around the park against international players.
You're better off looking at other leggies, MacGill, Qadir, Yasir Shah all put a bit more into their run ups
