See that menu bar at the top of the page? Scroll over the “Seattle’s Worst Trades, Draft Picks & Free Agent Signings” section and you’ll see a little drop-down. Here, you’ll find the master list simply in List form (i.e. without all of my expository opinion on each particular move).
You’ll also see sections for the Mariners, Seahawks, and Sonics. Here, I’ve split up all the moves from the List by team, and separated them by General Manager. So, you can see all the crappy moves Seattle teams have made, as well as who was the General Manager at the time. Blame! It’s all about where to place blame!
