Can't say "great". I would say he's doing an unpopular but necessary task that won't pay off for the big club for another 1-3 seasons. He's got to be above average in drafting and some of these guys have to pan out as surprisingly effective NHLers, while his lesser picks still fill out Rochester and maintain a competitive level there. Bryson, Laaksonen, and UPL look like they could be those surprises. Davidsson, Pekar, and Samuelsson might be that good also. Mittelstadt has to turn a corner, while Dahlin was a can't miss no-brainer.
His really meh signings and trades were mostly to acquire character guys that could be good for the younger players (some were cap dumps), while the organizational depth catches up during seasons Botterill knew they couldn't be a quality playoff team. I don't blame him at all for not paying more futures for more, quality players. Skinner and Montour were exceptions that were worth it (Skinner being a slight gamble).
To move forward with more aggressive moves, Botterill has to believe the organizational depth is up to a level that makes more draft picks expendable. If his previous picks keep developing, and he hits another 2-3 NHL worthy prospects this draft, the organization will be much better off and the time for bigger moves will be here, while the time for taking cap dumps will be gone.
