One man does not make a bullpen. And to fair Robertson before we traded him did the job as the closer. That wasn't the problem it was getting to the closer. Starters go 6 innings at best these days. I get diaz but outside of raley possibly and diaz who in the world do you want to see in the 7th and 8th. Thing is if you have a good bulpen you need 4 of those guys do get to diaz. Even if I include Raley the mets have just one. Hence they need 3 more at least.
