I think this is too much (hopefully not), and I'm going to explain why and what the goals for the season should be.
We have to remember that we are a bit thin of experience if we have a couple of injuries in our ten-man rotation, we have many new players to adjust and we can't still know if/when Isaiah will be playing.
I think 60 games is a bit too much for these factors. Anything beyond the 53 wins we've had this season would be very successful if we develop our young players in the process. What we must focus on is playoffs, we should at least take the Cavaliers into 6 games in the ECF.
This, along with at least a high draft pick in 2018, is what would bring ringchasers and players taking less money to play with us in the next and final step of reconstruction-development.
