Barrington has only started 7 games in the last two years, so I'm willing to give him a little more time. He's 6'1" 240 lbs.

Luke Kuechle is 6'3 238 lbs. Bobby Wagner, 6'0" 241 lbs. Besides lacking experience, Barrington lacks elite speed. At the Combine he ran a 4.91 40 yd. Kuechle ran 4.58. Clay ran a 4.67. Carl Bradford is 6'1" 252 lbs. and ran a 4.76 40 yd.

As a point of reference, Jimmy Graham is 6'7" 265 lbs. He ran a 4.56 at the Combine.

Rey Maualuga, a top free agent MLB, is 6'2" 255 lbs. He ran a 4.91 40 yd.

Size and speed is the ideal, but IMO the Packers' defense needs speed more than anything at that position...speed and sure tackling ability.
