Mariners' big offseason additions have horrifying comps that can't be ignored

There's an obvious way to be pessimistic about what the Seattle Mariners did this offseason. It simply involves pointing out that they lost Jorge Polanco and Eugenio Suárez, whose star credentials speak for themselves.

Of course, bringing back Josh Naylor was huge, and the club's two major additions have real upside. Brendan Donovan is precisely what the team needed both on the infield and in the leadoff spot. Jose A. Ferrer, meanwhile, has good control and closer-caliber stuff from the left side.
