What are you talking about? There's no difference in the types of players Simmons, Murray, White, Walker and Johnson can defend.
So having Walker, their most promising prospect in 7 years, on a team that needs all the upside it can get, currently being probably one spot away or in a battle (Belinelli) for rotation minutes, in his 2nd season, isn't enough? They need to bury him with an aging, fringe player, who hates the organization and is an ungrateful puke?
Simmons can't shoot or defend big wings. He's literally the worst possible fit.
