FG’s batting value projects them as the 7th highest value. That encompasses all offence, defence, and baserunning. Their projected standings has them at 13th in runs scored, but that doesn’t account for park factors as certain teams will easily hit high numbers due to their park dimensions (Cinci, Boston, Texas, Baltimore, NYY, Philly come to mind). Based on projected run differential they’re firmly in the top 10 at 9th, and no that’s not because their pitching is projected to be elite (only 10th in RA/G).
Edit:
And then you have Baseball Prospectus’ PECOTA projections. They have the Jays 2nd in the East behind the Yankees and only 5 teams (Yanks, Astros, Braves, Dodgers, DBacks) are projected to score more runs than the Jays.
