The Dallas Cowboys had the NFL's best offensive line last season, helping former running back DeMarco Murray top the league in rushing. The rich got richer this week when they inked LSU offensive tackle La'el Collins, a first-round talent who went undrafted because of a legal scare.

Collins was wanted for questioning by Baton Rouge police in the shooting death of his pregnant ex-girlfriend Brittney Mills. Although Collins was not a suspect, the specter of any involvement in a murder scared teams away from the best O-line prospect in the class. Collins spoke with police earlier this week and is still not a suspect. He met with several teams, but decided Dallas is where he wanted to be.

"I guarantee you this. I'm going to give this organization everything that I have and more," Collins said. "This is going to be the best offensive line in NFL history. Mark my words."

He's described in his NFL.com draft profile as a masher in the running game that can pass protect deftly, and dominate lazy rushers.

"Thick through chest and displays upper-body strength. Has strong hands and will snatch and control less active defenders. He takes defenders for a ride once he's engaged on the move. Loves to mash and intimidate opponents. Mean player.

"Can center pass rushers and end their attempt in pass pro. Utilizes length in pass protection and is acclimated to a pro-style offense. Able to run-block and pass-set laterally. Well-schooled and technically proficient. If he gets beat on a play, he comes back even harder on the next snap. Finisher. Can come in and play guard or tackle."

His ability to pass protect might be especially valuable to the Cowboys. Quarterback Tony Romo has battled injuries the past two seasons, and they only ranked 16th in the passing game as opposed to first in the running game.
