It's a possibility, i can't doubt that yet.
My only gripe with this Sri Lankan team (3rd favorite Test nation) is the tail. A few CWers have been calling it a great tail, I think its pretty dire.
You have a FAR superior top 5. I mean Ryder and Taylor could MAYBE crack it but no one else comes even close.
But the bottom 6 aren't that great looking.
Prasanna is okay but I'd probably rate Vettori as a better batsman. The guy is a good keeper but doesn't deserve to be batting at 7 considering the batsman before him.
Mathews hasn't impressed me at all so far in his career and while it is possible he could come off and all his talent could come to fruition he has done little to nothing at the top level of cricket.
So Sri Lanka have a possibly good (Mathews) number 6 and an okay (Prasanna) number 7, but after that it tails off rapidly. We play Vettori at 8, Sri Lanka plays tailenders. Tailenders who can handle a bat (just like my dear Jeets) but tail enders nonetheless.
This is why to me Sri Lanka's batting is never going to be a great lineup. You can score 700+ because you have a wonderful top 5, but you can crumble just as quickly due to a far weaker bottom 6.
That said NZ's strong bottom 6 (not so strong with both Martin and O'Brien there though) probably won't help much if our top 5 go missing.
