When Pierre Garon left Sundays game in New Orleans with a foot injury, the biggest opportunity of Aldrick Robinsons NFL career hit him square between the numbers.I knew I had to step up, Robinson said of his first NFL regular season action. The game plan was to go to P a lot. So I knew the ball was going to be coming my way.Robinson caught four passes for 52 yards and a touchdown in the Redskins 40-32 victory over the Saints. If Garon is unable to suit up in St. Louis he was limited in practice the past two days Robinson could make his first career start against the Rams.Thats what youre hoping he could do because theres no doubt hes talented enough to do it, Offensive coordinator Kyle Shanahan said of Robinson, a 6thround pick out of SMU in 2011. You never know until a guy gets thrown into that situation. Aldrick came in and we didnt miss a beat. He stepped it up, did what he was supposed to do and I was real happy for him.Robinsons second reception resulted in a milestone he wont soon forget. With the Redskins leading 10-7 in the second quarter and looking for more, the 23-year-old who spent all but one game on the practice squad last season ran a shallow slant and snagged Robert Griffin IIIs pass just as he crossed into the end zone.Then, in the third quarter, the Redskins faced a second-and-19 when Robinson made another impressive catch, hauling in a ball that was thrown slightly behind him for a 29-yard gain.Opportunities come, and you have to take advantage of them, Robinson said. That was an opportunity I knew I had to take advantage of.Just as important, Robinson has proved to himself and the coaching staff that he belongs.It was a big confidence booster, he said. It allowed me to see where I was at, and let me know that I can play on this level.
