Several sources have indicated Herbert will be returning for his senior year. Chris Miller who is a good friend of the Herbert family states that Herbert is a lock to return.( 2 different sources discuss this) Another article indicates Herbert's status is similar to Andrew Luck when he was picked to go very high in the NFL draft but chose to return for his senior year. Unless he is projected as the #1 overall in the draft in 2019, I think that the chances are excellent that Herbert will return.
