Is the size of bats being overplayed? They are not wider, and the stumps haven't decreased in size or width and with only willow being allowed in the making of the blade, bats will reach a natural maximum size before the become to dry and break too soon and negate performance. Sure bats today give batsman more bang for their buck, but a good ball is still a good ball. My take is that batsmen now days have adapted to the modern game, where as the bowlers (in general) are still too catch up. Hawkeye has given bowlers as much assistance as thicker less dense bats have for batsman, with umpires now willling to give more decisions and the fielding team having the ability to appeal against a not out. For me the 4 fielders outside the circle needs addressing back to 5, to even things up.
