Srilanka had a hard time against Zimbabwe in ODI despite being top seeded team but IMO T-20 is the only true format which can be level the field and where low rank team could compete with anyone and if given chance regularly ( priority to associate) with proper backing they could do wonders in spreading the game.
Not a promising update for lankans just before the Asia Cup, i know deck would be different but still they need to some brainstorming.
