Weakside tackle Pat Williams just needs a partner who can play the run with aplomb. Shawn Price, Leif Larsen, Tyrone Robertson and Ron Edwards all saw action at strongside tackle, but none were noticeably effective.
Buffalo simply needs a standout, high-round tackle, someone who is used to succeeding. It should find one with its second-round pick (36th overall).
Notre Dame's Anthony Weaver is excellent against the run, with less-than-ideal size, but very good technique to keep opponents' hands off of him and stay his ground at the point of attack. Weaver possibly projects as a first-rounder, but he may be available early in the second.
Washington's Larry Tripplett is bigger than Weaver, and he succeeded as a nose tackle for the Huskies. His forte is holding the line and making sure nothing gets through his gaps. His style is similar to Ted Washington's.
Alabama-Birmingham's Eddie Freeman is taller than Weaver and Tripplett, but is lighter than both. He could be the best athlete at defensive tackle with excellent strength and an explosive first step. He can get upfield. He's not as good at stuffing the run as Weaver or Triplett.
Mississippi State's Dorsett Davis has the height and weight to dominate in the run game. He can move as well, but doesn't play with enough leverage, which is a sure-fire way to get blown off the line in the NFL.
If the Bills look at ends, it will be in the lower rounds because they already have Aaron Schobel, Bryce Fisher, Erik Flowers and Kendrick Office.
