I think Celtic fans may have forgotten that CBS teams typically started the year shooting poorly. This didn't happen too much the last two seasons.
I'm not going to dig into the stats right now to prove this. Someone else can or I will try to later. But in his first 4 seasons, players like Bradley, Crowder, Thomas, Sullinger, Olynyk, and Turner always seemed to start the year slowly. I remember fondly all the trade ideas to get shooters on our roster in the early parts of each season.
But as the year goes on, the Cs get into rhythm in their offense and start making shots.
One of the things I've learned from watching CBS style is that shooting percentages don't always correlate to wins. Playing the game the right way with discipline and effort and unselfishness leads to wins.
