Exactly.
I understand the fair expectation for Franz having a better 3p%, but it's utopic to believe that everyone will have better % in the same season. A couple examples, Suggs had a great 40%, will maintain it? KCP had great % in teams that were contender with MVP caliber players with him. Will be the same with us and our usual spacing issues? Finally, old grandpa Ingles had the best 3p% in the team and is gone.
Some will improve, others will regress, that's normal in an NBA season, but until now we're far away from being a top shooting team.
