The downside is monetary cost, which, if significant, will impact the front office's ability to address other roster needs (C). Maybe Anderson hasn't signed yet because he's holding out for big AAV $$$, a long-term deal, or both. Mondesi will come relatively cheap and is a switch-hitter who could be used in a platoon with another bargain bin SS. Consider that Andrus, who played in 112 games and turned in 1.1 WAR last year, hits lefties a little better than righties. I agree that Anderson probably has the most upside of these three, but there is some potential for downside there.
