Boys! By that logic, the message is that Lankans are "entitled" to lose games outside Lanka till (1982+69) 2051, on a consistent basis??? Talk sense man! India hardly took the game seriously until 1983 WC.
The point I am making is that Sri Lanka needs to bolster its away batting performances, to supplement the efforts of Mendis and Murali. Even the most premier batsmen, Mahela and Sanga have an average differential of over 10 in their batting averages. But I am confident that all it will take is just one win. Take it from a SL fan.
Heh, I definitely can't wait 'til 2051!
Seriously though, those comparisions just aren't valid. A tour to WI or Aus 50 years ago would have been one hell of a culture-shock, even for an experienced sportsman -- nowadays, a trip halfway across the world isn't quite as unusual. Plus, there are so many ODI tournaments going on that even young players shouldn't get overwhelmed by an overseas tour.
Perhaps that's the problem with Bangladesh? On the one hand, it becomes obvious sooner that "here's a side that's close to Test standard"...but then, they don't have the years of consolidation/struggle that SL had, giving touring sides a bloody good game but not getting Test status. Perhaps it's those years that allowed SL to grow strength in depth (relatively speaking) rather than just one or two good players?
A definite problem is series length -- if all a team gets in foreign conditions is three warm up games (one of which gets rained off anyway!), they're going to lose the 1st Test. If it's a three Test (or even shorter) series, where's the come back from that? Too much pressure on the youngsters, who go a few steps backwards as a result.
SL's last series in England was great fun -- if only there were two more Tests in it! I honestly thought they'd go on from there to beat the overseas problem, but it's not quite happened. Closer, though.
It makes a nice change having SL described as needing to find more batting depth, mind.
