It's not controversial, it's stating an absolute as fact. Again, there's no way of knowing. Over a long enough timeline, yes, it is very likely a player will get worse as he gets older. It's almost a given that 97 year old Braun will be worse than 32 year old Braun. But in the short-term, it is unreasonable to suggest that a 36 year old will definitely, assuredly be worse than a 32 year old. Also, what exactly is "worse" - what if he is cumulatively more productive in the next 5 years than he was in the previous 5 years? Is he still worse if he tails off at the end? Really? Its "almost" a given that a 97 year old Braun will be worse than a 32 Braun year old. Almost? So you're still not willing to go out on that limb, huh? As for your thoughts on him being more productive the next 5 vs the last 5, you're going to need to show some links that suggest Ryan Braun will do that. Because it sounds like you are taking statistically unlikely events to prove a pretty shaky point. Doesn't seem like a strong position? Here is mine for my somehow someway controversial POV: The Quick Opinion: A resurgence in 2015 was halted by back problems near the end of the year requiring surgery. Braun proved he could still play at a high level, but his days as an elite-level hitting outfielder are likely over. http://www.fangraphs.com/statss.aspx?playerid=3410&position=OF
