Knight Riders have a strong and vibrant bowling attack. Brett Lee has been generating pace, Rajat Bhatia has been difficult to go after and Sunil Narine is back at being mysterious after a comparatively not-so-productive time in international cricket. But it is their batting which has appeared off colour, with only Eoin Morgan managing a half-century. Manvinder Bisla, the hero of the final last year, has been consumed twice by his own aggression, while Jacques Kallis, Manoj Tiwary and Yusuf Pathan are yet to show any intent. Gautam Gambhir has had starts, but as he often reiterates, the team needs to fire collectively.Royal Challengers Bangalore's batting has an intimidating aura around it. It has also been bolstered with the addition of AB de Villiers and their bowling attack, despite the seesawing fortunes of Vinay Kumar, has shown incisiveness. However, their bottom half of the batting order appears thin, at least on paper, and will be tested if their top falters against Narine and Co.However, they have received a boost ahead of this game. Brendon McCullum, who kicked off the IPL in 2008 with a blazing 158 (still the highest score in IPL cricket), is available for selection. The New Zealand captain had to postpone his trip, having to wait to recover completely from the hamstring injury he picked during the home series against England last month. He joined the Knight Riders camp on Wednesday.
