Hilton is still the man in Indy, and will be Luck's main weapon and target until Indy drafts or stumbles upon a better target. Don't forget that good defenses are capable of game planning around stopping Hilton because Luck has one of the worst receiving corps in the league. Dontrelle Inman was a good midseason pick up, but he isn't a long term answer.
The Colts need to draft a WR with their first round pick or one of their second round picks, then take a chance at another in the later rounds.
