He should be. Playing for the Rhein Fire, the 49ers-allocated running back had one of the most spectacular games in NFL Europe history last week to lead Rhein to a 24-20 victory over rival Frankfurt and push the Fire atop the league standings at midseason with a 4-1 record.
Robertson earned NFLE Offensive Player of Week 5 honors after breaking loose for 188 yards on just 12 carries, including touchdown jaunts of 90, 50 and 20 yards. The 90-yarder was the longest run and also the longest touchdown run in league history. His 15.7 average per carry that game also is a league record.
"You don't plan on that kind of (game), and you don't expect it," Robertson said. "But if it happens, you're excited about it. You're kind of overwhelmed."
Robertson - who had a three-day training camp tryout with the 49ers last summer, then was signed by the team in January - has been overwhelming opponents in Europe since the season began. He leads the league in carries (90), rushing yards (592) and touchdowns (6) at midseason and is on a pace for a 1,184-yard season, which would shatter the league record of 1,057 set by Barcelona's Mike Green last year.
Robertson knows this is the kind of thing he must do to have a chance to break into the NFL this season. He is not guaranteed an invitation to training camp with the Niners in July, but his play in Europe no doubt is securing him a ticket.
"I feel for my career, this is the best thing I could have done," Robertson said. "If I just went into (training) camp, they'd still have some questions about what I can do. This gives me a little something I can point to. My main focus when I came here was just to get on film so people could see my skills. The success I've received so far, some of it has been very surprising."
But Robertson won't be resting on his laurels. With the Niners stocked at the running back position, Robertson knows he will have to continue to shine at a high level of play even to have a chance to make San Francisco's roster this summer. But that will come later. He still has some shining to do in Europe.
"A lot of people here talk about the (NFL training) camps," Robertson said. "But my focus is on this Rhein Fire thing right now. I really don't concern myself with what's going on in July. I have to worry about what's going on right now."
And it's showing with record production on the field.
