As the Cleveland Browns (0-12) get closer to clinching the No. 1 pick of the 2017 NFL draft, there is a chance the team will not use its top selection on a quarterback.

The Browns have what one source close to the situation described as an "astronomical grade" on Texas A&M defensive end Myles Garrett, a blue-chip prospect who could dramatically upgrade Cleveland's defense. The Browns are enamored with Garrett, according to the source.

Taking Garrett could upgrade Cleveland's defense, but it would also likely deny the Browns the chance to take the top-rated quarterback in the draft. Cleveland, however, is still doing its due diligence in scouting quarterbacks. Browns scout Lake Dawson, who once starred at Notre Dame, has spent an inordinate amount of time in South Bend, Indiana, scouting Fighting Irish quarterback DeShone Kizer, according to a school source. Many expect Kizer, a junior, to announce that he will turn pro as soon as this week.

The Browns could also look to address their need at quarterback through a trade, as some believe they will make a run at New England Patriots quarterback Jimmy Garoppolo after the season. The Browns and Patriots have been trade partners twice this season.

Even if the Browns select Garrett with their No. 1 selection, Cleveland still has an extra first-round draft pick, formerly of the Philadelphia Eagles, to pursue the quarterback it wants.

The Browns lead the San Francisco 49ers (1-11) in the race for the No. 1 pick.
