Two key pieces in the magical 2015 Postseason run for the Astros were Colby Rasmus and Luis Valbuena. Both will be remembered for their surplus of power but the lack of consistency. The Astros resigned neither of them this offseason, so they will each be searching for new homes for the 2017 season.
Because of their power-hitting capabilities, each would fit well on a team lacking power in the outfield (Rasmus) or a corner infield spot (Valbuena). Rasmus seems to have more appeal to a World Series contender simply because he has more experience and proven postseason success.
