Is There a Mark and Priority in Mark?

I think that, you know, we're imagining now, I obviously coming out of Mark study. There is always a sense when you spend enough time in Mark,. You see how Mark has interlocked the stories and sayings and phrases. And then you see how Matthew uses that same story to a very different effect. It's really, really hard not to be persuaded for me that there's some kind of Mark and priority there. The book was full of all kinds of things I never heard anybody making points in the other four.
