I honestly haven't watched a whole lot of Bradley, but could he be Robin Lopez-ish? Robin has started to step out to 20 feet, has the same kind of flat shot, good rebounder, smart player, good defender. I couldn't find Robin's measurements, but draftexpress has his twin Brook with a 7'5" wingspan and 9'5" standing reach, and NetsDaily tweeted that Robin has a 7'6" wingspan. Bradley had a 7'5" wingspan and 9'4.5" standing reach at the combine.
Bradley is very fundamentally sound and knows his limits. Good footwork, efficient, rebounds pretty well (he actually boxes out which is great to watch - and the reason why he gets a lot of offensive boards in the G-League), lots of catch-and-shoot inside shots near the basket. I'm a big Bradley homer but I want to see how he'll play against the more physical bigs who will likely push him out of the paint. From what I watched in the G-League highlights he didn't post up and call for the ball very much - he needs to add muscle to keep from getting pushed around but once he gets stronger I think his footwork will be commended more than it is as he'll be able to keep his balance and finish.
