That's probably the most realistic outcome, but Heyman tweeted yesterday that he is the top priority for Philly and that they have an offer out for him (he's still testing the market like everyone else). With Dombrowski there, I would think that deal gets done at some point unless the Jays offer blows them out the water, and I just don't think Atkins does that with 5 catchers on the 40 man and 2 of them being top 10 prospects in the system (Kirk/Moreno). If his price falls, and Philly bows out, then maybe there's a chance.
Springer (Mets), Bauer (LA team), and LeMahieu (Yanks) seem destined to sign elsewhere. Sugano is probably going to a West Coast team or NY. There are still good players out there, and the Jays will end up with some of them (they are buyers when supply is high and demand is low so they'll get good players), but I don't think any of the top names will be included in there. The trade market might change that though (Lindor, Cincy players, Kris Bryant, etc).
