I think everyone knows that Kemp, Jones and Ethier are the best three in the OF. However, there are other factors involved than just talent and production.
Pierre has been brutally bad but he is not this bad and would start for a lot of teams. As we saw with Hart in MIL, when there are viable options, then one bad slump could force Kemp to ride the pine and split playing time. It remains to be seen what actually happens.
In theory, yes, you would have Kemp playing everyday.
