I'd stay away from both. Too much risk & future uncertainty about the drugs. A number one pick in my eyes, better be clean as the wind-driven snow. That's how valuable that slot is to any franchise. Besides, my thinking of acquiring a formidable defense starts with grabbing a total package ILB/MLB that's a game changer.
How do you pass on a potentially GREAT linebacker like Ragland, which in all likelihood, will be staring the Colts in the face with the 18th pick?
If Ragland isn't there, defense at BPA. If not, then Conklin/Billings if BPA.
An opinionated side note : This team better get serious creating a very good defense, otherwise, the Colts will not hoist another VL until they do.
