Read his post again. He is whining how they would have won in a full T20 game because they had 5 wickets down.
Read my post on how DL works. It factors in your highest run overs scored. England didn't score that many and were consistent throughout their innings. Furthermore its the best method possible method. Until people can come up with an alternative...without drastically changing the laws of cricket (a team only gets 5 wickets is downright stupid), then we can talk.
Also people are talking so much of this safety net, but one is also forgetting the wet ball moves around more and with more moisture in the air the ball can seam/swing easier. Its harder to grip yes, but it zips off the pitch giving you a little extra pace (and that too late in which it can be hard to read it). It works both ways in the end, Windies bowled well enough to restrict the DL target. Everyone knew the rain was coming...why did England bat first? Everyone knows the DL method provides a little extra incentive to the team chasing.
