Before analyzing this week’s deadline deals, I need to go on my annual rant about how the trading deadline works. I hate the concept of a rental player, which seems like the baseball version of the ringer you bring in for your company softball game. “Oh, Tony? He’s a former college baseball player we just hired to be our new Director of Directionality. His job is to make sure all the staplers are facing the same way. Hey, is our playoff game with you this Sunday?” Tony is, of course, let go Monday, retiring with 3 HRs in your 12-11 win.
