Any trade of Adames at this year's deadline HAS to return a prospect more valuable than the comp pick the Brewers would be losing by trading him a few months before his free agency. I just don't see a contending team desperate enough for SS help to pony up the prospect capital it should take to pry the starting SS from a team currently leading their division with eyes on the postseason.
From the Brewers' perspective, it would need to be an AL team to send Adames to (i.e., don't improve NL postseason competitors). Maybe the Astros, Cleveland, or Red Sox are fits at this point as playoff hopefuls with limitations/issues at SS, but frankly that's about it for potential suitors.
I just don't see a good reason to trade Adames at this point - and that's just fine by me.
