Robinson was in the 12 man test squad only two weeks. He's far too good for D2 batting line-ups, let alone a glorified second XI batting line-up. He deserves to be in D1.
He's also less under-cooked than the rest - due to his time in the 55 man England squad, meaning that he returned to training earlier than any other bowler in this game other than Crane. Plus of course, as a bowler, he gets multiple lives. If a Northeast or a Brown play one under-cooked poor shot, they're most likely walking off the pitch. If Robinson bowls one under-cooked poor ball, he goes back and bowls his next.
On the face of it, bowling a side out of 176 and 221 is a really good effort. Especially with a weakened attack. But realistically, to win the game, it needed to be 150 maximum both times. Had we held all our catches, it probably would have been.
