I'm sorry, but I don't see the need for a shooter either. What we need to do is take less contested jumpshots.
And Stevens has to balance his rotation such that we don't have a line-up again like we had against Denver (Rozier/Smart/Ojeleye/Morris/Baynes). That's a unit that's not a result of a roster flaw, but just bad coaching.
Brad will continue to run lineups like that, like he does every year. Until the rotation gets set around January, there will be tons of lineups that make you go "what is Brad thinking?", 90% of which will fail (and make people say "that lineup was obviously gonna fail, why is Brad being stupid"). The 10% or so that suceed, though, will pay off big time in June in the event of injury (like last year) or the team needing a change (like starting Gerald Green against the Bulls).
And then Brad will do the same thing next year, and people will make the same complaints, then praise the unorthodox lineups in June. Rinse and repeat
