Bills looking to tackle draft: While the Bills retain moderate interest in Riley and Denver unrestricted free agent tackle Trey Teague, look for Buffalo to use its first-round pick in next month’s draft on either Mike Williams of Texas of Miami’s Bryant McKinnie, the two highly-regarded tackle prospects in this year’s lottery. GM Tom Donahoe personally scouted the campus workouts of both players and, on Wednesday, he and coach Gregg Williams spent extra time with Williams. A right tackle for the Longhorns, there is some question as to whether Williams can switch to the left side in the NFL, and the Bills made him do several drills with a left-handed stance. Buffalo would prefer to rid itself of 10-year veteran LT John Fina after June 1, when the impact of releasing him would be somewhat ameliorated on their salary cap. They could move second-year right tackle Jonas Jennings to the left side or draft one of this year’s two top prospects. What they almost certainly will not do, despite rumors to the contrary, is use the fourth overall choice in the draft on Oregon QB Joey Harrington.
