For me (and in this format), I think "Top Tier" help is pick and choose.
Take for instance, Mike Conley - he is easily a top 8 PG in the league and would probably put up better numbers on a different team.
Lionel Hollins clearly favors Rudy-Marc-Zach as their Big Three. But even with that, Mike Conley is perhaps the most complete PG out there, and a very good shooter from deep and from the field - as well as a great defender (2.2 steals last season - tops among PGs I believe.
What type of increased production are you expecting from Mike Conley?
I'm expecting a slight ppg increase from him, which I can see him doing easily. He will probably alternate with KG for 3 or 4 on the dpeth chart scoring-wise.
I'm expecting an increase in his assists, from roughly 7 to around 9. His steals will remain among the tops in the leage (2 or more).
I believe Conley can easily produce stellar defense, leadership, 16-17 pts, 9 assists, 2 steals and 3 reb season from him in this format, and do it efficiently.
