I think I would rather see them go Flowers, Suzuki and McCann all for less than it will cost just for Grandal. McCann can play 1B if needed and all three have power off the bench. With Culberson around to be your super sub, I think you could afford to carry three guys who are primarily catchers and with their age it's likely 1 of the 3 would be on the DL at any particular time. McCann might be your manager in the future.
Then sign Pollock and use the rest of the money elsewhere.
