How many games would this team win against 2016 competition if all of these Twins players were together in their Twins prime?

The way I see it is the starting rotation would be the best in baseball as would the bullpen. The lineup would be by far the best in baseball. Excellent bench as well. All that said 115 wins should be possible.
