Tyreke Evans is not a talented enough defender to handle the League's small forwards. They are going to be asking A LOT of Davis and Asik defensively. Basically they have two great defensive players, and three shooting guards who don't play defense.
depends if those small forwards can post him up and abuse him. Most couldn't post him and abuse him. Remember the question is can they make the playoffs- there are plenty of playoff teams without elite small forwards. The West have got...the Clippers (Matt Barnes), the Grizzlies (T Prince), the Rockets (Ariza), the Mavs (Parsons), Portland (Batum)....that's off the top of my head. Now yeah they might have size/ length on Evans but he could burn every one of them to the hole- it just makes it a different kind of match up.
If they came up against Durant or Lebron then yeah he'd struggle mightily, but he sees them 4-6 times a year at most. It won't be their concern because there's no huge disadvantage. Other teams will also be so busy trying to stop Davis that he'll get so many open looks and cuts.
I know what you're saying but it's not as relevant to them making the 7th/8th seed. It's more relevant to a team looking to be a contender.
