Again do you trust Russ Atkins to trade Bo Bichette. Of course the Cubs would jump at the chance.
I'm not against trading any Jay for the right players... but given where the Jays are at now, the deal can't be for futures... it has to be for established MLB talent that you would need to argue could make us better now. And those are hard to make - and are controversial.
I don't really see a deal, but I will give an example of something management might view as attractive if they are trying to win now.
I'm looking at the good Cubs established position players . The only thing I could see Toronto management justifying is something like Dansby Swanson+ another young good player that is already MLB established to a decent level (Nico Hoerner or Chris Morel). And that is only because we know management seems to highly value players with significant defensive value based on recent moves (Matt Chapman, Daulton Varsho, KK). For example Bo's WAR is 4.9, and Swanson's is 4.8. It is only close because of Swanson's defence.
Dansby Swanson is far superior to Bo Bichette defensively (he has 2 gold gloves), but he is also the far inferior hitter that is 4 years older and turning 30 in February, with 6 years left at $160 million. Our hitting coaches tend to makes these average hit, great glove players, hit worse so it makes them extremely frustrating.
Would I do that trade - no. That contract from his 30 to 35 season could easily turn into an albatross.
But I do know management likes great gloves, likes acquiring "smart" players for those who make many mistakes (like Bo), and likes cost control (and Dansby has a fixed long term contract and Bo does not).
