I think the most important point is that Kafka would need to get a HC job. The Giants get nothing if he leaves for another OC job.
One thing that I think is worth noting is that Kafka must have a pretty good reputation in the league. After the terrible season the Giants offense just had, it's a bit surprising that not one but two teams interviewed him for head coaching jobs.
