Seeing as how there is no OL rotation and under Cav there won't be, I would expect defections there. I would also expect a QB or 2 to look to go elsewhere. No guesses, just a thought. I wouldn't be surprised at RB either. The management of that roster is confusing at best. At the time, many had no issues with Green leaving to TCU. In hindsight, that was a huge loss IMO. So even though some positions we look "deep", the reality is we probably one guy leaving away from having little to no depth....
This isn't a knock on Riley. Every coach, on every team experiences attrition.
