[3] Stepping into the starting lineup as a sophomore, Sosa made an immediate impact for Rutgers at his left tackle position, paving the way with Jeremy Zuttah and Cameron Stephenson for Ray Rice's successful debut as a freshman, the school's first 1000-yard rushing season since 1994.
The line only gave up eight sacks all season, the fewest in all of Division I-A football, and helped propel Brian Leonard to his NFL career.
[citation needed] In 2007, Sosa had been named to the Outland Trophy watchlist along with his bookend Zuttah, and won preseason all-conference selections by Athlon and Street & Smith's.
Sosa continued his strong play in 2007, blanking all-Big East defensive end George Selvie, in addition to Jameel McClain, Johnny Dingle, and Angelo Craig.
This was in spite of dealing with a nagging knee injury that caused him to miss several games, which limited his level of participation in the NFL Combine and his Pro Day.
