49ers Webzone senior writer Al Sacco joined popular Niner Empire online show Ronbo Sports this week to discuss the team and the numerous offseason roster competitions.

Sacco discusses the battle for the two guard spots along the offensive line, including what Joshua Garnett has done to prove himself to Kyle Shanahan and the coaching staff.

Some fans weren't fond of the decision to extend the contract of guard Laken Tomlinson or even the 49ers picking up the fifth-year option of defensive end Arik Armstead. Sacco explains why San Francisco made these decisions and what the team likes about the two players.

Other topics of discussion include which wide receivers are likely to make the team, the looming suspension hanging over second-year linebacker Reuben Foster, and what the NFC West rival Los Angeles Rams have done this offseason.

The conversation with Sacco begins at about the 9:25 mark.
