Here's something to ponder. Before central contracts and when they had the great overseas players here like Ambrose Walsh Donald and the English players we're gough, Malcolm etc 80-85mph was very medium paced I was late 70s 80 on a good day along with a few others and we were trundlers. You had to swing it or do something. From what I see now mid 80s is quick. Now it's relative to what you play against. If your a club player that facing mid 60s every week late 70s is going to seem a bit sharp. One of my early games was against mr Donald and I was out my league he broke my finger second ball and I stood there thinking he can kill me at will and I have no say in the matter.
Now as far as TV pace is concerned I heard a rumor that 4 or 5 years ago to try and hype up the cricket on TV sky were tweeking the speed guns up to make it seem quicker and more interesting and that was from a reliable source.
It's all relative but I do personally feel that we are going through an era of lower pace and it happens, but I think if you can produce a few Anderson's which England used to be renowned for ie swing bowlers we would not do bad at all. Talk to a lot of ex pros and they will tell you there are different types of quick.
