Poll: Colts' position weakness

The start of training camp is three weeks away. The Indianapolis Colts used the offseason to fine-tune some things rather than make wholesale changes.

Enter linebacker D'Qwell Jackson, defensive lineman Arthur Jones and receiver Hakeem Nicks. Gone are center Samson Satele, safety Antoine Bethea and guard Mike McGlynn. Re-signed were running back Ahmad Bradshaw and cornerback Vontae Davis.

Those were just some of the highlights -- or low-lights, depending how you look at it -- of the moves made by Indianapolis.

The Colts hope the offseason moves will be enough to help them close the gap with Denver and New England in the AFC this season.

But, of course, there are some who still don’t believe general manager Ryan Grigson did enough for that to happen.

Which position do you think is the Colts’ biggest area of concern heading into training camp?
