I think Rao can bowl a bit too, maybe a little less than Raina. But Rao is also a solid fielder and hard-worker in the field, so if he can find a place in the regular eleven it would be ideal. I'm so glad we have all these young, athletic players coming in and pushing Yuvraj for his spot in the team. Sachin, Sehwag and Dravid are solid veterans, and add to that Kaif, Yuvi, Raina and Rao, along with the excitement of Dhoni, and you've got a deep pool of talent. Of course, there are the likes of Gambhir, Ganguly(?, comeback), Dhawan, Uthappa, Laxman (maybe done but never doubt his talent), and others. Things looking good for India. If Raina can develop into a guy that can bowl 5 overs a match regularly and bowl them well, India can just insert him into the #7 spot instead of Yadav. Think about how great this would be:
Sehwag, Tendulkar, Kaif, Dravid, Yuvraj/Rao/Raina, Dhoni, Rao/Raina, Pathan, Agarkar, Harbhajan, VRV/Zaheer, SuperSub: Sreesanth? Powar? Raina/Rao? who knows?
As you can tell, I'm excited about the fresh talent we have here.
