I thought Edwin Diaz was great fun. I loved Narco, and he was at times a brilliant closer, but I trust people who know more about it then I do to make the judgement. There is plenty of people who report that Diaz' peripherals are on the way down south and that he's potentially very close to becoming a somewhat lesser version of himself. Leaving aside the fact that he's had bad runs already. Devin Williams had a bad April but otherwise was there or there abouts the best reliever in baseball for the last couple of years. I'm not sure what the actual best way to judge a reliever's production is - it probably isn't ERA - but I think I'd be 60/40 to saying Devin Williams will be better then Diaz over the next 3 years and therefore if you think that's what you're getting and it's 18 million cheaper then there you go. All that being said, I wish the industry wasn't so obsessed with roles and $ because it sure was fun to have him to play for us.
