The averages point is spurious in general terms. 90% of the time when we discuss individual bowling stats, we are discussing exceptional players, and it is a factor. Waqar striking 40%? faster than Wasim meant fewer overs bowled by players averaging 30.Hmm, I understand what you're saying (although your bringing averages into it is spurious). My problem with strike rate is that a bowler only has so much control over it. The rest is down to who he's bowling too. Take Davidson and Rabada. Similar averages, but Davidson was bowling in an era of predominantly defensive batsmanship so ends up with a strike rate of 62 at a very low econ, while Rabada is bowling in an era of attacking batsmanship with poor defence so ends up with a s/r of 39 and a fairly high econ. So while I agree than taking wickets quickly is all well and good (and probably helps your WpM, if you play in fewer draws) I feel it's only a partial reflection on the bowler at best and the rest is all down to the batsmen. But I see people refer to strike rates on here without considering the batting as a factor.
SR, like average should be era adjusted, particularly the last few years. Rabadas 40 might be worth 50 or 55 in Davidsons time.
