This was something I found that I think does a good job of breaking down Tannehill.
One particularly great point in the article that I wanted to point out:
Last year, Cam Newton was considered a project because he only had one year of Division-I experience in a spread offense. Ryan Tannehill has a year and a half experience as a Division-I quarterback in a pro-style offense and two more as a receiver. I think he has as much understanding of a pro-style passing game as almost any college prospect in this draft.
