Namely, guys willing to let him run the O, including playcalling.
It’s a wonderful stepping stone position for future advancement but does require a person to be willing to stay in background and tend to the more routine O matters.
At least O’Connell was able to skip the step of going to another team to ‘prove himself’ as LaFleur did.
Vikings don’t know how good of a play caller O’Connell really is. Think about that.
Heck, maybe O’Connell will hire a legit OC so that O’Connell could be a traditional executive type HC? Who knows?
