Marino may not be a teacher, but I would be interested to get his impressions on the areas that Tannehill needs to improve. Like others on here, I doubt that one can teach pocket presence, but what did Dan do to keep his as sharp as possible? What did he do to mentally prepare himself for a big season? What did he do to minimize other distractions in his life? etc
What I'm saying is that for just about the first time in the 17 QBs AD (after Dan), we have a very smart young man with some very good skills who has the potential to be a good to very good QB and it would be good to progressively build a relationship between the two, if possible. This is entirely academic if either party isn't amenable. However, Dan still loves the Dolphins and Ryan comes across as very eager to learn.
Apparently Brett Favre helped as an assistant high school coach in his local Hattiesburg area and the team was very successful. Favre was considered the gunslinger of gunslingers, but he actually surprised everyone how well he taught the young players how to prepare as footballers and what to look at to exploit Defenses. Sometimes old champion QBs can offer some great tips to anyone prepared to listen. Maybe Ryan should also seek some one on one time with Brett Favre. He had a good release as well.
