When I saw this trade floated yesterday, my immediate thought was "this makes too much sense not to happen." Williams is 100% a Brewer-type player ... versatile, good defender at multiple positions, very fast, good baserunner with a very high OBP, surprising pop, but short in stature. It will be very interesting to see if he is chosen as the "SS of the future", or if that honor goes to Cooper Pratt, who is quite the yin to Williams' yang both stature and playing-style wise.
I expect that Williams will be in Milwaukee at some point this year. And the "little guy energy" the team will have with him, Durbin and Frelick will be fun to watch.
Sproat is the type of high ceiling arm that the Brewers always seem to get the most out of. It wouldn't surprise me to see him make up much of Peralta's expected production as early as this season.
