I appreciate Trevor's viewpoint, but if anything we are seeing players playing longer. The steroid era lengthened many careers, no doubt about it. Now that the steroid era is ending, career trajectories are going back to normal. In any case, it has been known for a while that: 1. It is key that players hit free agency before they are 30 (the younger the better) 2. Players get the maximum salary when they first hit free agency, and further contracts are not guaranteed. There have been metrics that show for years when the decline starts. Predictive metrics are taking this knowledge into consideration when they predict players like Dozier and Plouffe will decline. And let's be honest -- we all know Dozier and Plouffe, although they had good years, are cooked. I appreciate Plouffe's opinion, but for accuracy, I give it a D-.
