You're ignoring that players are no longer doing this.......they just aren't. You can project how you'd feel all you want, but just look at the last three or four years.
30/31 and older is now prime? On a site where people say all the time NOT to sign guys into their mid-30s, now it is a good idea? I'm confused by that sentence. In a league that is getting younger and younger? I don't see that.
What do other players have to do with Buxton? His circumstances are special and unique, creating perfect conditions for a deal that makes sense both ways. Very few position players with his ability have as much motivation to lock up financial security at this stage.
Also, I don't recall saying anything about signing Buxton into his mid-30s being a "good idea." I said if he hits the market at age 30/31 as a star-caliber player, he'll have no trouble landing another large contract. You're the one talking about market precedent; that happens with numerous players every single offseason.
