I don't think he has played himself out of the 1st round but unless he has an outstanding combine I think he has played himself out of the top 10......
Of course he will go in the first, but usually the top LT in the draft is going top 5 or top 10. I think he's likely going to be graded in the 15 to 20 range which I think is likely below where the Saints will pick. With the Carr injury I see no way they don't pick around #10 or lower.
