Veteran cornerback Morris Claiborne has been hit with a four-game ban for a violation of the substance abuse policy, sources tell Ian Rapoport and Mike Garafolo of NFL.com (on Twitter). Claiborne, they hear, plans to appeal the suspension in hopes that it will be overturned or eliminated. 
Claiborne stands as one of the best available free agents left at this stage of the offseason, but the impending ban could explain his extended unemployment. Recently, the Vikings kicked the tires on the cornerback, but did not sign him.
Claiborne, 29, spent the past two seasons with the Jets and has played on one-year deals for the past three seasons. He hasn’t really excelled since his 2016 season with the Cowboys, when he graded out as Pro Football Focus’ No. 12 ranked corner in a limited sample of seven games. Last year, Claiborne graded out as just the No. 75 CB in the NFL out of 112 qualified players, per PFF.
That kind of explains why the Jets are looking to have Darryl Roberts as the starting CB opposite Trumaine Johnson rather than signing Mo… At least, Johnathon Harrison won’t be the starting center thanks to signing Kalil.
Vikings would be better off bringing back Captain Munnerlyn
Vikings might be better off signing Captain Crunch.
