Ronald Curry interviewed for Saints Offensive Coordinator

In Shanahan's system, it's been observed that for some reason it can take QBs a year before they get truly comfortable (Matt Ryan comes to mind, but there may be others I can't think of at the moment).

But McVay's QBs tend to have immediate success in their first year (Goff, Stafford). So there are differences between the two systems (Shanahan's run concepts are particularly distinctive to his tree).

I will say that Purdy stepped right in running Shanahan's system. And, I guess it depends to some extent on if we are talking Kyle or Mike Shanahan. I think Kyle's version is more QB friendly and quicker to learn. I mean, the system has more or less worked no matter who is at QB for them. That being said, I would prefer the McVay version over the Shanahan version.
