With Castro already getting late round feedback and Harris likely a UFA they both should return, Higgins comes back He is one of the favorites for the Butkus and at best He would be a round 5-7 player this Year, He should return, Lachey is facing a very strong TE class coming off an injury which would slide Him into Day 3 , He should return and ball out and get that round 1/2 area next Year . Jackson comes back if the NCAA approves the Year or why would Iowa have made the petition in the first place if He wanted to enter the Draft, Schulte should return as well He would be a UFA , Cooper if He feels will not drop to round 2 should go but He has been dropping in all the mocks lately and People stereotyping Him to Safety , If He gets the feel He will be pushed to Safety and round 2 He should return .If CB and round 1 go. Just My take .Iowa gets a bulk of that Defense back and there will be hell to pay
