Well, clearly we don't know until they set foot on the court. But given the film I've seen, I feel pretty confident both Brooks and Poole will be far better three point shooters than MAAR. By next year? I don't know, we'll see. Poole has Stauskas type range, and Nik was certainly a better three point shooter as a freshman than MAAR has ever been.
Again, my point is real simple. If the MAAR we saw over the final 15 games or so is the guy we'll have next year, he'll keep his job and play big minutes. But if it's the guy we saw early in the year, he's going to get pushed hard for playing time if indeed Brooks and Poole are ready (and sure, they may not be).
