Can't believe I was once Rajib's biggest fan.
Pace bowling isn't easy. You have to either have crazy innate talent (Amir, Asif, Cummins, Pattinson) or develop incredible skills (Vaas, Zaheer) to even be decent let alone good or even great. I'm not asking for that. I just expect BD pacers to at least average 40, not 80 and 100.
If the WI could play 4 pacers, why can't play 4 spinners. At least they will create the odd chance and bring the RR down and won't get tired from bowling long spells.
