The Washington State receiver ended speculation about his potentially entering the NFL draft with Sunday's announcement.
Marks made his decision public on Twitter, penning the following message:
While Marks, a former four-star recruit, played early at WSU. He redshirted last season, something we wrote about in detail here, leading to conjecture that he might choose to enter the draft rather than spend a fifth year in school.
Marks finished the 2015 season with 104 catches for 1,192 yards and 15 touchdowns. A Biletnikoff Award semifinalist, he will likely enter the 2016 on plenty of preseason All-America lists.
