he shot 71% from the line in the playoffs his first year. And he's been at 60+ his whole career until this one.
it's definitely possible.
keep going back to my doc rivers is trash idea. His teams don't practice, and he's on Stotts' level in terms of making adjustments. And while he talks up his players in the media, I don't think he really encourages guys behind the scenes (as evidenced by how quickly and easily he threw Simmons under the bus just moments after Game 7). All season long, whenever criticism was levied against Ben's lack of shooting, he pointed out Simmons' defense and passing. But the moment it actually cost him a playoff series, he did not hesitate to eviscerate him in public.
Simmons needs a guy who will give him some tough love. Needs someone who will empower him to shoot and be OK if he misses, because the potential is too great if he can figure it out. I don't even think he needs a three point shot-- just a floater/FT line jumper and he will be the perfect P&R release valve with Dame. Maybe send him down to Phil Beckner with Dame and lock him in a gym this whole summer.
