The inside linebacker spot next to Donald Butler is one of the roster's question marks.

A rookie could be the answer.

On Monday, the Chargers formally hosted Kiko Alonso, an option with the No. 45 overall pick. The visit was part of the ex-Oregon inside linebacker's tour that, all told, includes scheduled visits with eight teams and a private workout Sunday.

Alonso was with the Vikings on Wednesday. He'll see the Titans next week.

Seventeen teams interviewed him at the NFL Combine.

Much — often too much — can be made of which team is speaking to which player and what that may mean for the team's intention to draft him. That said, the Chargers could very well consider Alonso, a projected three-down linebacker who'd fill a need if the team decides Jonas Mouton, a 2011 second-round pick, is not its answer.

There is another reason teams line up to evaluate Alonso face-to-face.

The start of his Oregon career was marred with alcohol-related legal trouble. He found stability in sobriety and set career highs as a senior after two arrests in a 15-month span between Feb. 2010 and May 2011.

Alonso was first convicted of a DUI, drawing a suspension for the entire 2010 season. His second offense came after, during a state of apparent disorientation, he broke into a home that neighbored a party and fell asleep on a bed. Days later, he reportedly pleaded guilty to criminal mischief and trespassing while agreeing to enter a diversion program.
