Liking this - I think in addition to weighing individual metrics on players across the diamond and how they contribute to the overall W/L performance of the team over the course of 162, the Brewers have to assess what moves can be made to strengthen a team weakness in a short series/playoff format. Power/HR in the lineup is this team's primary weakness - if it means sacrificing a couple regular season wins to add an impact bat or two at the deadline at the expense of defense or positional versatility so the lineup has a better chance of slugging in postseason, the Brewers have to make that move this year.
If the Brewers want to make a splash move at the deadline (i.e., unexpected trade that sends a ton in return for an impact player), I think SS is the position the Brewers should target and go after a guy like Henderson (Orioles) - but there just aren't any SS this deadline that are obviously on the block - so this would seem to be more of an offseason-type trade option the Brewers could look to make by packaging a bunch of their prospect capital. So that makes the obvious position to upgrade 3B, and Suarez is that guy.
