Yordan is a good example of what I am talking about. He's 28.313. His contract lasts thru age 31. There is almost no age-related risk, and you get almost three perfectly prime years. With Marte (and others), you generally get two prime years, and 3+ years of decline.
This is why a relatively rich team like the LAA haven't been .500 in 11 years. They added Pujols, Upton, Cozart, Rendon, Hamilton, Wells, etc., at an age where they had no reason to expect much production.
