IKF at 3B is gross, and I expect Kiermaier to regress to below average offensively. Other than that, there's a lot of volatility in the lineup. Could be good, could be average, or if Vlad/Springer/Kirk/Varsho don't bounce back, then it could get ugly. I think the team is hoping for not only bounce backs/regression, but also hoping that depth can help compensate over 162.
The fact that the Jays decided to go with an injury prone KK, 40 year old Turner, and backup in IKF definitely leaves the door open for prospects in the minors, both short and long term. The development of the position players projected to start in AAA (Horowitz, Orelvis, Barger, Palmegiani, Jimenez, maybe Roden) will be crucial this season.
