Is Seantrel Henderson off Dolphins' board?

The Miami Dolphins have shown a decent amount of interest this offseason in local product and University of Miami offensive tackle Seantrel Henderson. The Dolphins sent a heavy contingent to the Hurricane's recent pro day – including head coach Joe Philbin and general manager Dennis Hickey – to check out Henderson. And Henderson was often projected as a potential late-round option for the Dolphins, who are desperate for athletic offensive linemen.

But the latest news on Henderson may have ended his chances of landing in Miami altogether. ESPN’s Adam Schefter reports NFL teams were notified last week that Henderson tested positive for marijuana at the combine in Indianapolis. For Henderson to fail a drug test this close to the draft is telling.

If I’m the Dolphins, I am taking Henderson completely off the draft board. Henderson has ideal size to be an NFL offensive tackle. But he was suspended multiple times during his tenure at the University of Miami, and this latest transgression during this important time is another red flag. Henderson joined the Hurricanes as one of the top recruits in the nation but never lived up to his potential. He’s not doing anything to erase that fact during the pre-draft process.

The Dolphins were considering Henderson as a potential steal late in the draft. He has the size and athleticism that you can’t teach. But is Henderson trustworthy enough to invest a draft pick on him?

At this point, the best move for Miami is to only consider Henderson as a rookie free agent. That would provide a chance for the Dolphins to coach up Henderson with minimal risk in the event he doesn't mature and learn from his mistakes at the next level.
