I guess it's all relative. I mean, you're right in that he's not going to win any dunk contests. However, if you look at 0:10, 0:21, 0:35, and 1:45 in the video linked below, he can get off the ground pretty well. I think I said, "pretty explosive leaper," which I'll stand by. I think he'll continue to develop as an athlete. No issue with your disagreement, though - I'm sometimes prone to hyperbole.
I do agree that it's all relative, but the bottom line is that Tim Finke is a really good player (we both agree), so use of specific adjectives is less of an issue.
The thing that I really like about Tim Finke is that he already has excellent fundamentals. Not only is there no aspect of his game that is lacking, but he is very good at almost everything and has a complete game. He has very good basketball IQ, good passer, good handles for his size, pretty good quickness, and very good shooter.
I think his shooting will also set him apart in college. He is the epitome of the new generation of shooters (good form and very quick release) rather than a purist (i.e., two stage, high elevation and release at highest point, e.g., Ray Allen). The advantage is that Tim Finke can get his shot off very quickly without needing much space.
I agree that Tim Finke has a very good chance to become a McD AA, I'd be surprised if he is not. I actually believe if he was more "explosive," he would be a top 5-10 player, not just a McD AA candidate. Independent of Michael Finke, I hope we do get him. An excellent player, worthy of the multiple scholarship offers he will get.
