They didn't give Montgomery, Butler, Kelly, etc a rotation spot this spring, and if they kick Montgomery out of the rotation for Hendricks, then their best bet from the internal options won't be likely to go a full SP's workload. Quintana and Teheran combined cost about as much as Lackey+Anderson, so it's not a matter of finances that would hold them back either. That said, if you have Lester/Q/Hendricks/Teheran, another SP isn't a huge need, but there isn't a whole lot else to spend on either. I think it can add up fairly quickly. Let's say you buy a guy in FA, instead of adding Teheran.....That's probably an extra 5-10 mill in payroll. Darvish being the biggest target, that would cost more..... You're going to need 3-4 bullpen arms, that's going to add up. Maybe 25-30 mill? More, if you keep Davis or trade for Britton..... And you've at least got to look at a possibility of adding a CF. Quintana + Teheran + Darvish at 30M + 25-30M towards the bullpen is basically the same payroll as this year's team. Maybe you can't get a Jay replacement, but those bullpen estimates are probably high(Montgomery is in the pen in this scenario) and you've got several CF lying around(Happ, Almora, Heyward, maybe Burks) without dropping Jay-money on one. Is that the path I think they'll go? No, but it's not all that elaborate a contortion either. Trading for Teheran wouldn't close any doors, unless there's a similar valued pitcher you like better that you can't trade for with a more depleted system.
