I think they will look to acquire Lee and sign one of Shields/Iwakuma. They'll be fine.
Shields will likely command a salary similar to Lester's in the offseason. They'd only be on the hook for 1-2 years of Lee at $52.5 million, but he'd also be ages 36-37. And they'd have to trade for him. Iwakuma is already 33 and will likely get a 4-year deal in the $18-20 million range.
In other words, they'll end up having to pay nearly as much for those guys as they would have for Lester. More if you assume Lackey would have played for below-marked wages in 2015.
