The Bears signed all their draft picks and gave Brian Urlacher the contract he wanted, but they still weren’t able to open a holdout-free training camp.

Kick returner and wide receiver Devin Hester refused to show up for the opening practice and is staging a holdout because he’s unhappy with his contract, Mike Mulligan of the Chicago Sun-Times is reporting.

Hester has two years left on the four-year, $2.86 million rookie contract he signed as the Bears’ second-round pick in 2006. He is scheduled to make $445,000 in 2008 and $530,000 in 2009. The Bears could fine him close to $15,000 for every day of training camp he misses.

The Bears and Hester’s agent, Eugene Parker, have been negotiating an extension, but Parker and Hester apparently don’t think the Bears’ offer is adequate.

It would be tough to determine how much money Hester deserves because there’s never been an NFL player quite like Hester. He’s unquestionably the best return man in football, but he so far hasn’t contributed much as a wide receiver. This year the Bears hoped he could become a more significant part of the offense, but he’s now missing valuable time working with the Bears’ quarterbacks.
