I wouldn't say it's the end of free agency, but the end of league wide wanton FA spending, at least for a while. Even if the "extend them young" movement fully catches on, there will always be a few players who will accept the risk and gamble that they will be good enough (and stay healthy enough) to hit the FA jackpot. And some GMs are going to extend a young talent and get burned when they don't become the player it seemed they would, and that will dissuade them from employing the same tactic in the future. That said, I think most of the best young players will be extended at a young age, and up to and through their primes. This would of course reduce the number of 150M+ contracts being offered. Bit even as things currently stand, such contracts rarely work out well. Manny and the first ARod deal did to some degree, but more often than not those deals are given to players already at or nearing the end of their peak. Gambling on potential future production is invariably a smarter play than paying through the nose for past production that isn't likely to be repeated, and smart GMs realize this. Players will still hit FA, but far fewer of the best ones will, at least until they are in or nearing their decline phase. This may prove to be wrong, but imo the young, smart GMs who are extending their young talent are likely the vanguard of a industry wide movement that will take hold for at least some period of time. And really, it's not something that the players and the union should be opposed to.
