Five years ago, Troy Tulowitzki was the best shortstop in baseball. In 2014 he lead all shortstops in batting average, on-base percentage, slugging percentage, wRC+, and FanGraphs WAR; and he did so in just 375 PA, despite WAR being a counting stat. That represented the culmination of a six-year run in which he led all shortstops in wRC+ and WAR, while averaging just 113 games per season. So when the Rockies started shopping Tulowitzki in 2015, it was a big deal – even if he had difficulty staying healthy.
The package that the Blue Jays sent the Rockies in July of that year was not quite befitting of that level of talent, though.
