I don't think they should have an offseason deadline because what would happen is many of the signings would simply happen right before the deadline, just like the trade deadline. However, I find it ridiculous and condescending for the author of the article to suggest that the reason we find this offseason slow and boring is that we've been "programmed" for low attention spans. Yes many have low attention spans, but it's very clear this offseason is been one of the slowest in memory and still isn't finished by a longshot, and got a late start, and that isn't good for the sport.
I care infinitely more about what's in the best interests of fans than about the interests or salary gains or losses among players vs owners. I would have no issue whatsoever if players or owners lost hundreds of thousands of dollars every year over some decision that would make the sport better for fans, and I think it's silly that fans back the players when it's against their own interests. Like the fans who cared more about the players getting a better collective agreement during the lockout than the fact that the lockout was denying them the sport they like to watch as consumers.
Anyways, this offseason ridiculousness is the fault of Boras and Boras alone. He has obviously created unreasonable demands for his players far above their market value. Every other significant FA has signed and they didn't get ripped off. I don't at all blame teams for being less eager to sign ridiculous FA contracts like Boras has convinced them to do in the past and teams rather putting that money into extending the young stars on their teams that have been severely underpaid forever with virtually no guaranteed contracts until now if they get hurt or flame out a few years down the line.
