Hmmm. I think he could have played a good Jasper. I really don't know how to explain. I obviously like him better as Edward but he could have played a sweet, quiet, and charming character like Jasper. However he could NEVER have pulled off Emmett in my opinion b/c I always viewed Emmett as this huge, bear-like guy (which Rob clearly doesn't fit this description). Good question :] I never really thought about this before.
