I think DK will probably be asked to limit his play to 4 games. Probably end of the season just in case of injuries. Here's why.
1. If DR is as good as we think he could be gone as soon as the end of year 2. Pros already want him.
2. If DK can red shirt this year that would still leave him 3 years to start
3. If DR goes down for 1-2 games HH has proved he can win, and his throwing motion has much improved.
DR like all college football players is not eligible for the draft until he has been in college for 3 years.
