Gayle - The closest comparison, in terms of intrinsic quality, is Aamir Sohail. Goughy's comment is spot-on. He's an amazing hitter of the ball but doesn't possess the mental toughness required to augment technical ability.
Sarwan - I am truly at a loss to explain Sarwan's failure in test cricket. The first time I saw him, during his debut series against Pakistan, I remember thinking he'd take the mantle of the world's best batsman from Lara in a few years. I think in terms of technique he possesses all the elements necessary to succeed at the highest level - he can negotiate swing, seam and absolutely hammer spinners when he feels like it. He's got a class wrist and even more importantly, when at full form, he can anticipate variations and adjust his game accordingly. I can only conclude that his problem, like a lot of West Indians, lies somewhere between those two ears of his.
Chanderpaul - His temprament is on a completely different plane compared to the rest of the West Indian players. His main strength lies in playing an auxiliary role - a line-up where he has to carry his team will be resilient from time to time but never dominate attacks. Chanderpaul's considerable reserves of concentration are focused inwards - he isn't the type who can inspire the rest of his team with his words or actions, and that's visible on the field.
He comes of as somebody who's very focused but ultimately selfish - even though that's manifestly not the case. However, preceptions are what matter and in a way Chanderpaul's success is actually the failure of the rest of the team. In a good team, his contributions will never stand out to casual scrunity and he'll never get the accolodes he deserves.
Bravo - Again, Goughy's comments are spot-on. Bravo's presence in the test team and WI's reliance on him is the biggest indication of depleted cricketing stocks in the country.
Samuels - I haven't seen the resurgent Samuels play, however, the old Samuels shouldn't have been anywhere near the test team. He lacks the temprament to survive in testing conditons; furthermore, he also lacks the ability to dictate the tempo of the game - in fact, sans Gayle on roads, West Indies do not possess a batsman who can mould the tempo of a game at will.
Again, consider Ponting, Gilchrist and Hayden for Australia, Tendulkar and Ganguly for India, Pietersen and Trescothick (Stewart earlier) for England, Sangakkara, Jayasuria (De Silva in the past) for Sri Lanka, Graeme Smith, Gibbs (Rhodes, Cronje, Klusener, Pollock in the past - they were trully blessed) and Boucher for South Africa and Yousuf and Inzamam/Saeed in particular for Pakistan. Regardless of their failings/averages/successes they all had one thing in common - they tried their best not to let the bowlers dictate the terms. They were all proactive - while the WI batsmen in general, including Chanderpaul, seem unable or unwilling to do so. In Chanderpaul's case, owing to his inherent class, he is successful inspite of this - while the rest obviously fail.
Chattergoon - He's a nothing player. Not a long term prospect by any means.
Marshall - The kid is definitely talented. He reminds me of a young Imran Nazir in WI during the 2000 tour. He's got flamboyance and charm by the bucketloads - however, again, he seems to flounder and wilt in front of testing bowling. Whether that's a lack of temprament or something else, I am not sure.
Ramdin - What WI would give to have a Ridley Jacobs right now.
Baugh - A walking wicket.
Taylor - Simply isn't consistent enough. The problem with the current crop of WI pacers is that while all of them are promising, none of them rise above the rest of the pack. This is a problem they've inherited from their predecessors - Dillon, King, McLean, Rose - and until they find a geniune match-winner they'ren't going to win any games.
Edwards - Should be that match-winner.
Powell - Not test class.
Collymore - Past his best and not suited to the current WI attack which lacks a leader. He's a pure stock bowler and shouldn't be playing with three other stock bowlers in a team.
Collins - If it swings you can expect him to pick a couple of wickets - if not - he's fodder.
Devon Smith - Walking wicket.
Dwayne Smith - Walking wicket.
Nash - Who?
Findlay - Who?
Baker - Who?
Johnson - Who?
Morton - Walking wicket.
Rampaul - Who?
Fletcher - Who?
Overall Impression: Not enough depth and no stand-out cricketers (sans Chanders who is the wrong kind of standout).
