I love the KK signing. The Jays needed a strong defensive 4th outfielder who could cover CF and who could start a couple times per week if needed, which most likely is the case. Still should be good for 1.5 - 2 WAR. Will be interesting to see what other outfielder the Jays bring in to play LF or to split time with KK in CF.
I know some posters including myself preferred having Varsho starting in CF and most likely I think he should be given the chance everyday to play in CF. KK will play some CF as well, but I hope Varsho is the main guy at least since he's younger and under club control for another 3 years. Regardless, Varsho needs to hit better period whether he plays in CF or LF. At the end of the day, Varsho is hitting either #7-9 in the lineup, which will be fine.
I think the Jays will land one of the DH bats - Hoskins or JDM or maybe Turner. They could afford paying Hoskins or JDM around $20M on a one-year deal. Turner wouldn't be a bad option if you can't sign Hoskins and JDM and as mentioned could play some 3B if need be.
I still think the trade market is the best route to bringing in a third baseman.
