For me it is hard not to be optimistic when so few of the guys seems to be exceeding expectations and the team is still performing at a high level. Right now Yelich, Davies, Moose and Guerra are probably the only guys who I think are outperforming expectations. And outside of Davies I think the other 3 could maintain close to their pace. At the same time many guys look to have quite a bit of room for improvement in Shaw, Aguilar, Cain (with the bat), Braun, Chacin (looks to be turning the corner), Burnes, Jeffress, Peralta, etc. This team has played an incredibly tough schedule and has played well. The next 10 games are big but I see this as a team that has plenty of room for improvement.
