I see what you're saying but my opinion is based on current teams though, which aren't at full strength. I tend to agree with you though, a full strength WI team would be a handful for anyone, especially if Gayle and Pollard have good days with bat and ball.To put a full strength Windies side on par with Bangladesh is pretty harsh, in fact at full strength we'd definitely give both Pakistan and NZ a good run... Just a year ago we drew to NZ in NZ so to say they're streaks better is again pretty harsh...
Think the problem lies in the depth of the Windies side, Pak just had Riaz come in and take a 5wh and not one fast bowler is capable in that Windies side outside Roach Edwards and Taylor of doing anything close to that... The three at full fitness is pretty strong, granted not as good as Pakistans, but second in my opinion... Coupled with a full strength batting line up of the likes of Gayle and Sarwan, with Darren Bravo improving all the time, getting ready to replace an aging Shiv, and Dwayne whom is definitely capable of getting his test average up to at least 30... NZ can only really boast Taylor and Vettori, while Pakistan can only boast MoYo, and U. Akmal when he decides to learn how to play test cricket...
Whilst I reckon Pakistan are the strongest of the sides, at full strength Windies would give Pak a good go and just outgun NZ in my mind, though this is pretty far off happening with our seamers, and as our depth is non-existant NZ probs have the edge in that matter...
Btw, one poster (sorry can't remember who) said that Taylor had done nothing since England, and whilst that's completelu true, he's also been injured for the duration since that test match, never being close to full fitness, always playing a test then missing one etc. which obviously does no favours for him...
If full strength, NZ would have Ryder, who is fairly formidable in tests up the order, but sadly we've seen little of him due to injury. NZ's batting always looks great on paper, with the batting going almost to 10 but the mindset within the team isn't right yet.
