This would be a very intriguing pick on several levels. First off, Milliner is far and away the best corner in the draft by almost everyone's estimation. Milliner is massive for his position at 6'0 and 200 pounds, giving him the unique ability to match up one-on-one with larger receivers.
While the Browns desperately need help on the offensive side of the ball, there is nobody worth taking that high for them. Only left tackles are worthy of such a pick in this year's draft, and Cleveland already has Joe Thomas.
By drafting Milliner, the Browns would be pairing him with Joe Haden, one of the best young corners in the NFL. With both of those corners behind a revamped front that features Jabaal Sheard and the newly acquired Paul Kruger, Cleveland could have an excellent defense.
