"I have a lot to work on and I'll be the first one to say that. I'm the toughest person on myself," said Colombo, a 6-foot-7, 320-pound tackle from Boston College. "I just need to adjust to the speed, but I think everybody does. It's the first day in pads and that was probably a key."
Robertson, who saw time at center, guard and tackle during his college career, hasn't played any line position in the NFL. He did start 44 games at tackle at Tulane, but didn't play a down last season. Plus, the former fifth-round pick in 2001 is built more like a guard (6-3, 310) and has a first-rounder with a $3.1 million signing bonus breathing down his neck.
"That's part of football," Robertson said of competition. "We wouldn't need training camp if there wasn't a battle for every position. We want that, though, because it makes you better and it makes the guy behind you better.
"I know all eyes are on me and Marc, but I don't think I'd have it any other way. You only get to be in the spotlight so much, especially at our position."
