Former University of Miami offensive lineman Seantrel Henderson has the talent to be a first-round NFL draft pick, most observers believe, but after news broke this week that he failed a routine drug test during the NFL combine, he might be lucky to be drafted at all. Marijuana was found in Henderson’s urine sample, according to ESPN, which cited NFL sources.

Even before Henderson’s test results came to light, however, some insiders had their doubts about the tackle’s stock because of his past. He racked up three marijuana violations while playing in college.

NFL draft analyst Mike Mayock of the NFL Network told the Miami Herald last week:

“I think the most gifted player on [the Hurricanes] is Seantrel Henderson but he’s had off-the-field issues and on-the-field inconsistencies. He is a first-round talent that I don’t think is going before the fourth round — and that’s probably where he’ll go, somewhere in the fourth round.”
After the news came out, analysts and fans have continued to offer their opinions, many of them predicting Henderson will do even worse:
Henderson is the only top-level player to fail the combine drug test. Florida State defensive tackle Timmy Jernigan, who was expected to be among the first 50 players to be drafted, also did not pass. He tested positive for a diluted urine sample, Fox Sports reports, and now the NFL has announced Jernigan will not attend the draft at Radio City Music Hall on Thursday, according to NBC Sports.
Rounding out the last high-profile prospect to fail is LSU quarterback Zach Mettenberger, who also tested positive for a diluted urine sample. Mettenberger’s representatives says he has a good excuse, though. According to NBC Sports:
“Mettenberger’€™s agents said that the diluted sample was caused by him drinking extra water to combat dehydration.”
