It's obviously pointless continuing this discussion, it's going around and around in circles with the goal posts shifting every time.
You're never going to accept even the slightest criticism of Narine, and I guess there's no reason why I shouldn't let you believe he's the next Murali. By all means come back to me in ten years time with 'I told you so' if Narine ends up with 500 Test wickets at 20, but AFAIC the likelihood of that happening is tiny.
Speculating that Sunil Narine could become a Test ATG on the basis of his ability to bowl in T20 cricket, 6 Test matches containing one performance above the level of half-decent, and in spite of his complete inability to beat batsmen in flight because of his front-on action (flighting the ball fractionally more than David Hussey =/= beating the batsman in flight, ftr) is completely ludicrous.
"Is Narine going to be a Test quality bowler?" is one thing to ask after 6 Tests and a bowling average of 40. "Is Narine going to favourably compare to Warne, Muralitharan, O'Reilly, Grimmett, Bedi or Laker" is a whole other question. The former is a debate worth having. The latter is ridiculous.
Narine is good at what he does, and he'll go down in history as one of the most remarkable T20 bowlers we've ever seen. But in Test cricket, I suspect he'll be solid yet wholly unmemorable.
