Didn't Ranatunga call for a formal investigation?
When he calls for some cricket related thing, it usually gives me goosebumps. Fella is usually correct. He called some names as cheats some time back, and they were found to be involved with bookies, even his former team mate Jayananda Warnaweera.
I don't think players threw away the match. But starting from the squad there were issues.
1. Chaminda Vaas was ignored. He ran amock among batsmen in the IPL tournaments, re discovered his pace but ignored. It is well known in local circles, He was one of the biggest opponets to Mahela - Sanga authority. Murali was placid and no one had with an issue with him.
2. Sudden changes to team before final. Mathews as understandable, but dropping Mendis raised some eyebrows.
3. Decision to bat first, when it was well known that the dew settles in raised eyebrows too.
If players can provide evidence that it was the team strategy, then it wouldn't be an issue. SL people trust cricketers more than politicians. However Mahela - Sanga combo has much less trust than cricketers of earlier generation, saya Ranatunga, Jayasuriya or de Silva
The elephant in the room is that SL cricket is run by one of the infamous book keepers of Asia, who even managed to get in to parliament.
