There comes a point in every athlete's career when they realise they are what commentators often euphemistically refer to as "off the pace". They're not winning those 50/50 balls anymore, they're not as fast, they're getting injured more often and it's taking longer to recover. The same thing happens in competitive video games, and I think it's pretty much happened to me.
