This year is not like past year. This is the first year the Jays are legitimate championship contenders. Last year, the internal evaluations likely had the team on the cusp, but not quite where this front office has been working towards since they arrived.
Circumstances matter, and last year, the Jays were hovering a few games over .500 at the half. This is a data driven front office, and they likely evaluated the percentages, and made moves which would help their odds, but also continue to build towards their ultimate goal of constructing a roster, legitimately positioned to challenge for championships. Both Shapiro and Atkins have reiterated, when the time was right, the organization would have the resources needed to go after whatever was needed to put them over the top.
We will see at the trade deadline, but I expect Atkins to be in on many available targets, like he was in the offseason.
