Oregon quarterback Marcus Mariota is widely-regarded as one of the top NFL prospects in the college game, but the way Sports Illustrated hears it, the Ducks star is on even more solid footing than that."Scouts confirmed this week he Josh Donaldson Jersey 's the runaway favorite for No. 1 pick," in ranking Mariota as a No. 2 early candidate for the Heisman Trophy.Mariota ranks No. 1 among all NCAA quarterbacks in pa s efficiency with a rating of 218.0 (that would translate to a 152.5 rating in the pro efficiency formula). NFL Media analyst Daniel Jeremiah asked five NFL personnel executives for a Mariota comparison, to quarterback . Before the season, NFL Media analyst Bucky Brooks wrote that a faction of scouts believe Mariota in the 2014 draft had he chosen to be part of it.Of course, predicting Mariota as the No. 1 overall pick in September can't be more speculative not only from the early-entry standpoint, but also because it's no certainty that the team to eventually hold the pick will even need a quarterback most.For the season, Mariota has completed 71 of 96 pa ses for 1,135 yards, 13 touchdowns and no interceptions. He is only a junior, but is set to earn his degree in December. Mariota will decide whether to enter the 2015 after the season.*Follow Chase Goodbread on Twitter * Erick Aybar Jersey
