Who the **** cares? What is the opportunity cost? What is the downside?
If you don't think Ed Reed has value as a Miami staffer for both recruiting and improving the culture/practice of player development then I'm not sure what to tell you. He's been on championship teams at the college and NFL level. Of all the Miami alumni he's the single most qualified individual for building effective work habits within the program - film study, practice habits, leadership, off-field balance, etc. What Miami needs more than anything is to have a locker room full of players that hold eachother accountable and lead.
Does Reed have a more established resume of evaluation skills than Highsmith? No, but the coaches and recruiting staff can manage that aspect on their own like almost every other program does and has done for as long as CFB has existed. Ed Reed will not be the GM of Miami but I couldn't think of a better candidate to fill a traditional Chief of Staff role and impact the program.
