Of those 3, I think Foster Griffin was the trade that would have been the best fit the Twins.
Part of the reason Gausman's trade for a prospect haul was so small was because the Cubs took on the remainder of Gausman's salary. Although Tom P did open up the pocketbook to expand payroll for the trade deadline, I think taking on Gausman's salary would have been too much and other options were available, such as Griffin, which wouldn't have taken as much payroll commitment. Think of the offseason where we could have done a better job fixing the bullpen with the money we spent on Josh Bell. That's how I look at the Gausman trade possibility. We either wouldn't have been able to upgrade the bullpen or would have had to give up better prospects.
Ward is an interesting case as it seems like we already have too many OF or converted OF on the 40-man. The better solution would be to just call up Walker Jenkins and save the $3.5M in remaining salary. Yes, I know Jenkins is a LHB but, had the Larnach trade went through, that frees up the LH situation. You could have swapped Ward for Larnach and still called up Jenkins for Roden or Martin. Keaschall could then go to LF and Ward to CF.
No, I'm not secretly working for the Pohlads in suggesting that it's too much money. My point is that the money is always a factor in a trade proposal. I know both Zoll and Pohlad did say they were buyers and did buy at the deadline. Even with those statements, I can guarantee there was still a budget in place on how much to spend at the deadline, as most teams not named the Dodgers have. I think there should be a realization made that the team is flawed and there was no fixing an offseason's worth of missteps at the deadline, especially when you didn't trade any of the pieces that could have helped make the remaining pieces fit better, such as Larnach, either Jeffers or Jackson, and Bell if you could have found a suitor.
