On one hand, I wouldn't mind if the Jays did this with Kirk who is probably an upgrade at DH today over anyone the Jays currently have, but the thought of Kirk sitting on the bench 5 days a week so Panik and Tellez can play instead is enough to end that idea for me.
On that note, I hope more teams, including the Jays, stop gaming service time going forward. We can discuss the merits of doing it for development, but players getting paid earlier in their career is definitely needed in this sport.
