Decisions from two quarterbacks in the next month will have a major effect on the 2017 draft.

Notre Dame's DeShone Kizer and North Carolina's Mitch Trubisky both must decide whether it's better to return to school or declare for the draft.

ESPN's Todd McShay believes that both might be better off returning to school. The recent history of quarterbacks who return, however, isn't great. Players such as Ohio State's Cardale Jones and USC's Matt Barkley hurt their draft status by returning.

Kizer had impressive numbers in a disappointing year for the Irish: 2,926 yards, 26 touchdowns and nine interceptions. He had 23 starts at Notre Dame, winning 12. At 6-foot-4 and 230 pounds, Kizer has ideal quarterback size. The question is how soon he'll develop.

Kizer is not ranked among the top 32 by McShay, Mel Kiper or Scouts Inc. He has submitted his name to the NFL Draft Advisory Board to assess his chances, but if he's not forecast as a first-round pick, he might be better suited for a return to school.

McShay has Trubisky in his Top 32. Draft expert Dane Brugler of NFLDraftScout.com said Trubisky would be a top-10 pick if he declares and has him going third overall in his mock draft to Chicago. (He has the Browns taking Texas A&M DE Myles Garrett.) Brugler has Trubisky ranked fourth overall among draft-eligible players.

If Trubisky truly is a top-10 pick, he'd be wise to declare.

He started just one season at North Carolina, but completed 68.9 percent of his passes and shot to the top of most every quarterback rating. He's big, can stand in the pocket and is mobile. He has the attributes of an NFL quarterback, but he lacks experience.

His mother, Jeanne, told the Lorain Journal he is on track to graduate in December and will make his intentions for the draft known after the Tar Heels' bowl game.
