"...essentially the same team..."--No. I have posted frequently that Gardenhire should be fired--years ago! (and to take Andy with him). But, the addition of a bona fide hitter in Sano, the addition of Jepsen, E. Santana, and Duffey was a demonstrative improvement over the 2014 team. You must compare apples to apples for the 2014 and 2015 teams. "Essentially the same team.." implies a neglible difference in personnel, the use of team statistics is comparing the collective performance. If team performance is the criteria--simply compare the W/L records which is a distillation of all of the team peformance(s). In summary, the addition of Sano, E.Santana, Jepsen, and Duffey were substantial changes (improvements)--and the 2015 team was indeed much improved over the 2014 team. Though, I will claim that Molitor and his P.C. also contributed significantly to the 2015 team's improvement.
