With Lara in the side I'd consider the West Indies favourites, but to win the series we need to at least split the first two ODI's. Sarwan and Gayle are both outstanding ODI players and Chanderpaul has come very good of late, especially opening the batting. Powell batted well in South Africa, but it remains to be seen whether he can repeat. Dwayne Smith is useless. Ryan Hinds has great technique and with some confidence could go far.
Sylvester Joseph has potential but has Powell/Smith syndrome - lack of shot selection. Will be interesting to see how he goes.
Dwayne Bravo is one to watch out for with the ball. I'm not sold on his batting as yet, but with the ball he's been quite impressive in taking wickets almost everytime he comes on to bowl. He's also a brilliant fielder.
Ian Bradshaw is a useful lower order batsman and a Pedro Collins type left-arm seamer. He's a bit more accurate more often than Collins though.
Ravi Rampaul has really impressed me in his ODI career to date. I didn't like the idea of him being exposed in South Africa, but I have warmed to it as he is a very determined bowler and has a good yorker.
Corey Collymore will be better in the ODI game than he was in the Tests results-wise. He was consistently beating the bat and getting short edges in the Tests, but it's his economy that will come into play now.
Mervyn Dillon is a wildcard. He certainly has a lot to prove, but I haven't seen him play in about a month, when he scored 60odd and took 8 for 30odd in a innings for Queen's Park.
The expected tactic is that the West Indies will see how they go in the first three games and call in the pace if they need to after that (ie Edwards, Best. Lawson perhaps?). It should be a tight series, but we'll see how it goes.
