Before we start questioning the decision of Abul over Rubel, we have to take this in to consideration.
Hasn't Rubel been injured for a very long time and just coming back? He was the only pacer so far to play 2 Test matches in a row. Don't you think it's better we think about giving him rest? We don't want Rubel to get injured again because we overused him now do we?
I know Abul is a very erractic and inexperienced pacer but we also have to look to develop more pacers so that we can rely more on others rather than just Mash and Rubel. Just because we don't have the class pacers other sides do, doesn't mean we should bowl Rubel until he gets injured. Rotation of pacers is important.
