I thought they were looking at Puk as a starter, though I'm not sure if that is set in stone.
Hendricks is a good risk at that price. He's got a great K-rate to go with the success of last season. Diaz is a tough call, but he was by far the most valuable relief pitcher in the game just two years ago. I'd take him at $3.
My money league has limited spots as well as auction prices. I kept a closer because I had Hader at $18. Once you get past the elite guys, it's all about finding relievers you can trust. That doesn't always mean a guy who has closed for years. Maybe it is a guy who closed only one season, but he has multiple years as a dominant middle guy before that. Because stability is tough to find in the bullpen, it has value. That's why I spent on Roberto Osuna in my auction. He has been remarkably consistent for all five of his major-league seasons.
