I'm not interested about required rate until Blake is (in and) out. He's done it against us too many times before. If it's 13, he'll do it.
I’m mainly mentioning it because of the numbers of overs left. Scoring 10 an over for 15 overs is a challenge for anyone.
The difference between our fielding in that Somerset game, and our fielding in this game, is a world apart. Even ignoring that missed opportunity - it has hardly a drop.
