"We thought it was time to move [Colombo] up,'' Jauron said. "As I've said many times, I have faith in Bernard. I believe he's going to be a contributor to us for a long time, and he's got versatility, which is great.
"We just felt it was time to make the change. I can't have those feelings and not act on them. You've got to make the move."
On one drive in the third quarter Robertson allowed Kabeer Gbaja-Biamila to take down Jim Miller on one play and then the following snap Joe Johnson beat the left tackle forcing an arrant throw that Gbaja-Biamila picked off and returned 72 yards for a game changing touchdown. On pick Robertson was called for holding Johnson and still got beat on the play.
However, Jauron said
"I wouldn't want to make it sound like [Robertson] makes a lot of mental errors," Jauron said. "Obviously the false-start [penalties] would be described as a mental error and the [holding] penalty clearly. Assignment wise, he's pretty good. Technique problems at times.
Colombo played briefly at right tackle for James Williams against Minnesota and Atlanta. Then played left tackle when Robertson was pulled against Buffalo. The rookie will go up against Robert Porcher, who had 85.5 career sacks coming into the season, in his debut. Colombo believes he's ready and has come a long way since being manhandled by Phillip Daniels in a one-on-one pass rushing drill.
"I've learned a lot, especially sitting back and working on all my stuff with a good bunch of guys," Colombo said. "I feel like with this extra [off] week that I've got a lot of time to work on the things I'm doing wrong."
Gandy saw his first regular season action when he replaced Rex Tucker against Green Bay. Although, Gandy did start throughout the exhibition season, but at right guard while Chris Villarrial was out with a broken thumb.
"I'm just trying to get comfortable with the guys who are already established in there," Gandy said. "Just meshing as a unit and getting that cohesiveness going, it's going to be a real challenge.
"(But) I always thought I was ready, and now it's my opportunity to show it. I've been waiting for this chance for a long time, and I just want to take advantage of it."
