I don't recall any analysts getting upset about Morse being in the lineup... if I recall correctly he was actually a big sleeper pick in a lot of fantasy publications? But eh, maybe we read different sources.His career BABIP is pretty high. I would personally be quite happy with him hitting .270 or .280 with the power he's demonstrated (which is most definitely sustainable).
He'll walk more when they stop throwing him stuff to hit. So far, teams are still living with the expectation that they can expose him as a hitter.
