Speculation nation...huh?
Firstly, without Thomas, the Celtic's roster is different...isn't it?
Currently, Steven's has built the Celtic's system around Thomas' extraordinary talent.
Without Thomas, Stevens would've built a different system around whomever he sees best to build around.
This. TP. Al Horford may have averaged 5 ppg more and a couple of assists less. In fact, I know there is just one game, but the first day we knew we were going to live without IT, Bradley and Smart shot a lot more. With Isaiah, they have less freedom (which is logical, because Thomas has more offensive talent).
We set (even the other guard playing alongside him) many picks and all that stuff for IT. The whole system would be adapted to the new situation by a brilliant coaching staff. And don't forget with 5 good defenders we'd have some more points after stealing balls. Imagine a Smart/Bradley backcourt in defense night after night.
