Interesting thought. I think I like it. My initial concern would be fouls. Most games, we have a least one or two "bigs" sitting some of the first half with 2 early fouls. It's mostly been Tarik, but JoJo and Jamari have also had their own foul issues. In limited minutes, Perry has done well to avoid foul troubles. But with stricter enforcement of hand check rules, I'm wondering if Perry at the 3 might expose him to foul troubles as well as he tries to guard typically faster players looking to drive.
Perhaps "PE at the 3" is something to employ late 1st half or 2nd as we see how the foul situation plays out. Additionally, in limited minutes Lucas has looked like a player - so we might have more depth with our big men than many of us thought preseason.
An additional concern would be having one less sharp shooter on the floor. With a small sample size, PE has shown that he can hit the three. But most of us wouldn't pick him for a 3 point shooting contest. With @highelitemajor 's well-documented concerns regarding our 3 pt deficiencies, this lineup could exacerbate, not alleviate, that problem. That's less floor time for Selden, Greene, White, and/or Connor. Granted, as a group they've been anything but impressive from 3 land. But Selden's hit some recently, and I have to think that turns around for another 1-2 of them too (right?!)
Don't mean to dump all over your suggestion. As a said, I actually like it and think we should look to employ it intermittently during a game. Just not sure I would start with "PE at the 3."
