That's correct. Grilli and Biagini have been their best moves and their one big deal (Liriano/Hutch) looks good enough so far.
They haven't really done much other than some minor tinkering and that was probably the best thing to do in my opinion. You could argue that not signing EE was a mistake, but the opposite is true for Bautista. If we can continue to build minor league depth and make small, smart additions then I like the team going forward.
