maybe.....i could see them being better or worse record wise than any of those teams. Remember, in both Miami and Cleveland it took time for the teams to gel, and that was with Love/Irving and Bosh/Wade.
Now LeBron has a bunch of kids and a bunch of psychopaths and pretty much no one who can reliably drain a 3. I saw the numbers you quoted on Kuzma, KCP etc...but none of those guys is a pure volume 3 pt shooter. Ingram made less than 0.7 3-pointers a game last year. Before last year KCP's best 3pt percentage in his career was 35%--- at least he is SOMEWHAT of a volume guy with about 2 makes a game. Hart made 40% of his 3's but took less than 200 on the season.
They need a Channing Frye or Kyle Korver or something like that- a volume shooter who can reliaby hit about 40%. they actually need about 3 of those guys if you ask me.
Nobody that can hit the 3? I would have added a designated shooter but that's not really true, Wiggy.....
Ingram made 39% o his 3's.
Kuzma made 37%.
KCP made 38%.
Hart made 40%.
Rondo made 42% in the playoffs so he's certainly capable.
And James made 37%.
