0.5% chance the Cubs sign Bichette. His market would have to fall flat and with his age and the Jays interest I don't see them winning a bid.
The most likely FA's the Cubs sign will be the guys who are most undervalued by this year's market according to the Cubs and it's impossible to say who that will be because we don't know what other teams are willing to bid on players. Last year it was guys like Boyd and Rea, and before that it was guys like Swanson, Suzuki, Imanaga etc. Bellinger was an exception because they didn't have a CF and he was the only good one on the market at the time.
