Well, you could call that batting depth, imo.
Shortened the tail, then?
Anyhoo, surely in a WC final you trust the top order that got you there. Yeah, Matthews injury sorta threw the balance of the side, but replacing Matthews with two players (Perera and Kula) came at the expense of one of their better bowlers of the tournament in Mendis.
Hindsight and all, but it did stink when the sides were announced too.
