The Chicago Bears are making sure they have no shortage of outside linebackers competing for spots in the team's new 3-4 base defense when they head to training camp this summer.

Already having Pernell McPhee, Lamarr Houston, Willie Young, and Jared Allen in the mix, the Bears added to that competition with the signing of linebacker Sam Acho on Wednesday.

Acho that spent the last four seasons with the Cardinals after being drafted by Arizona in the fourth round in 2011. The 26-year-old really opened eyes as a pass-rushing outside linebacker in his rookie season, collecting seven sacks, but only had six sacks over the last three seasons.

Now, the 6'3, 257-pounder is more known for his run-stopping ability, and was given a positive grade in that department from Pro Football Focus for his efforts in the 2014 season. He was also credited with 31 tackles, one sack, one interception, and three pass deflections in 2014.

Even with this outside linebacker depth, it's still possible the Bears grab an edge rusher with the No. 7 pick, as there are a few tremendous prospects at the position that figure to warrant a top-10 selection. Youth is still needed and it would be nice to find a long-term stud to terrorize quarterbacks off the edge.
