Chicago Bears left guard Matt Slauson did not want to venture into the free-agent market after watching what happened to veterans a year ago.

Only three veteran guards got lucrative multi-year contracts in 2013 and Slauson wanted to remain with the Bears, so when the opportunity to re-sign came last week, he quickly took advantage of a solid offer.

Slauson’s four-year contract is worth a base value of $12.8 million with $4.9 million guaranteed. He will earn $4 million in 2014 after getting just $1.1 million in 2013. Slauson had an $815,000 salary with the Bears and triggered $285,000 in incentives this past season.

The Bears constructed his new contract in a creative way. He has a $3.17 million roster bonus for 2014 but $1.67 million is treated as an “OATSB,” or other amount treated as signing bonus. That allows that money to be pro-rated over the life of the contract for the purpose of the salary cap. Slauson’s deal includes $400,000 total in escalators for 2016 and 2017 that are based on playing time and partially tied to team performance. That could push the maximum value of the contract to $13.2 million.
