With all due respect I think Rana is over hyped and nowhere near as good ro effective as the other three. Rana just had a good day.
now lets not get into Rashid/Moin and Butt type arguments of past. :)
Rana has always been an excellent swing bowler. He has a tendency to lose his line and length though, but today's spell shows he has overcame this shortcoming. He is especially good against left handers. On top of it all, he's a genuine all-rounder, and can score some very quick runs.
