I never said that they were any good, I just said that they are our first choice bowlers which imo they are.
Oram was one of the best, if not the best bowler in the SLPL. Southee and Mills pretty much only bowl in the powerplay and at the death, which is part of the reason why their economy rates are so high. Obviously I'm being bias, but I do think that all three of them are better bowlers than their economy rates suggest.
FTR most other pace bowlers don't go for 6.5 to 7 an over.
Ignoring the minnows only four pace bowlers who have taken 20+ wickets operate at under seven; Sammy, Razzaq, Steyn, and Morkel.
