Don't worry, that will all change in the first test
You have a point re. Gayle and Cook though I reckon Cook is a lot better at handling swinging conditions. Just like to say that I reckon Gayle has finally developed a head under those broad shoulders. Thee way he played in NZ was fantastic, would like to highlight a particular point where Patel was pitching every ball outside the line of leg stump, trying to tempt him to do something and for about six overs Gayle just padded it away. He finally has some responsibility and looks to be prospering because of it. The fact that his run rate's been down is a good thing tbh and he will still punish a wayward Harmy and Anderson.
Yes we need things to go for us, but they arn't as unlikely as you are making them seem. Edwards has been consistent for the past year and proven he could take wickets when there's no swing around and Taylor is the same though had a poor series in NZ. Chanders and Gayle are in fine form and Sarwan is too good a batsmen to stay out of the runs. If the Windies selectors do as I want then they'll open with Marshall who has proven he can score runs at home opening against the best, and Devon Smith's last match also had him scoring runs down at 5.
If you add all of on top to the fact that there's no swing in Windies which means Jimmy will struggle, that and the fact that Harmison is an ordinary bowler in slow low conditions which is what the Windies are usually - I know Harmy's got a good record against Windies but can't for the life of me see him reproducing that. You got Broad who is just plain old average and Panesar who is low on confidence.
Things need to go for us but the chances of these things going for us in at least the first couple tests are not bad. Windies have a good chance of going out the first two tests level or even dare I say with a lead and then who know what'll happen from then.
