More and more mocks showing Sewell to the Bengals/being there at #5.

My opinion still is that if Sewell checks-out in pre-draft/combine workouts and interviews, he's a no-brainer. Makes your whole o-line better, your QB better, your RB and WR's better, and allows for more flexibility on the line when it comes to moving guys around, and immediately upgrades the talent level with a starter they likely won't have the cap room for in the off-season. He also serve as much-needed Jonah insurance, as that guy can't seem to stay healthy yet (AND if he improves next season like Whitworth did in his 2nd full season - you got 2 great bookends and a capable QB who can win playoff games).
Of course nothing wrong with trading-down and getting the #2 OT or IOL or a DE/DT/LB instead, but, if you're going to stay put and he's there, just do it.
