Your memory sucks. The thinking was trading Tulo for prospects, using Tulo salary dollars on pitching (and later, to resign EE), and using Goins or some other cheaper SS would be better for the team going forward.
Board majority opinion was Goins would put up 1.5-2 WAR, as a full time SS.
Also, it's April 26. This is a reactionary thread. Goins may or may not match his 2015 output. Probably not, but he'll be fine as MIF backup.
I remember in the offseason everytime someone suggested trading high on Shitabello, you were the first to defend him.
