Offensive Assistant Bracket?

Which of these NFL offensive assistants is most likely to be successful if hired as Rex's replacement?

I voted for Frank Reich. Born on Long Island had a brief stint with the Jets. The majority of his playing career n NY State so I like his NY ties. I like the idea of having a former QB, QB coach and OC as our HC. Grooming our next QB needs to be a priority.

quite frankly.......you either marry the OC/HC and their style of offense to whatever QB they draft......or forget it. Just as an example, Frank Reich knows nothing about spread offense......hiring him and handing him Mariota spells bad fit for both.

The combines and all-star games should provide a much clearer picture of who is really going to emerge as legit NFL material. Watching college games can be a trap at times.
