Arenado was never going to waive his NTC to play in Toronto, but kinda surprised he said no to the Astros. He must have only a few specific teams in mind.
I think it's becoming increasingly likely that the Jays 3B next season is going to come internally (Clement, Barger, Orelvis, Vlad occasionally). Maybe they do a buy low deal with Moncada but otherwise I don't see many options. The only Gimenez type of deal (where there's an overpaid 3B that another team would be looking to dump) that I can think of is Ke'Bryan Hayes, which fits Atkins' MO (controllable, great defense, s***** offense) but I'm assuming even Atkins would draw a line on how many defense-first players he can have at a time.
