The value for Tutu isn't this year, rookies Redshirt mostly on this team. We have Desean for what, 2 years? we will need a starting caliber speedster on a budget then, rookie contracts provide that. At that point we will most likely be facing cutting one of our starters as well for money vs production value or letting Van Jefferson walk the next year, we will be needing someone to step in.
I would not be surprised if we drafted another wide out at 4th round or higher again in the next 2 years.
This is a case of thinking ahead again, that's what our front office does, and its absolutely awesome!
