Frank + Rim Protector has been advanced stats gold since he was a rookie defending in front of KP. It translated to his numbers with Mitch last year. It's translated with Gobert for France. Pair him with a rim protector and you can focus entirely on offense at the next three spots (plus he can slot in at 1,2 or 3 so you have positional flexibility). If he's knocking down jumpers, he belongs in the rotation. Especially since we have a lot of offensive minded players.
Nice podcast discussing Frank's FIBA performance showing confidence, improved burst in first step, size and physique stand out, signs of growth even over just five months back, interesting tidbit about stepping into his jumpers vs planted takes...that's within the first ten mins.
