No I also suggested going to get someone else in a trade or sign someone cheap as more insurance. Someone projected to be a 1 WAR is a 1 WAR player in my mind. They should absolutely be able to find someone cheap who can put up 1 WAR if Shaw fails. They did it with Tauchman and Wisdom. Moncada sucks, they could probably get as much WAR from Madrigal, who also sucks. Virtually every time they spend several million on a position guy in FA it turns out badly, with the exception of catcher since that's what most catchers cost. Villar, Andrelton Simmons, Mancini, Descalso if he counts etc. Experience doesn't matter at all if you can't play.
I don't care what "a playoff team should do", I care about making the team as good as possible and you don't do that by wasting 6-8 million on a bad player. Either go get a 3B who doesn't suck or take that 6-8m and use it on their other spending to upgrade a mediocre player they may acquire to a good player, or a good player to a very good player. If they want to play a sucky player at 3B at least let him be really cheap. If they spend real money on someone i think he should be at least a 2 WAR type.
