(since I dont want to get in trouble with the mods and admins) If you wondered why I compared Patrick to McNeil is because several of their roles do sound similar to each other (Silverbolt, for example). And yes, in the VO world in general, Burton and Cummings would be US equivalents to McNeil, but I was actually talking about the dubbing circle (notice on this website how the most viewed VAs, both this week and all time are dub VAs)
As for describing him as Crispin Freeman + Steve Blum, take Freeman's voice and give him Blum's gruffness plus the type of characters he voices (Christopher Sabat serves as an intermediary voice-wise between Seitz and Freeman) (to put it this way, like Borderlands being Diablo meets Halo), and yes Freeman can do gruffer and deeper voices (its just seldom used due to his general typecasting but Id like to see him flex up his range)
