Tyrone Walker speculated that the moment might have been too big what with it being his first play in a Green Bay Packers uniform and a bunch of screaming fans ready to embrace him just a few yards beyond the Lambeau Field south end zone.

But the moment wasn't too big. No moment has been too big for the upstart Walker a 5-10 198-pound receiver who might be the biggest long shot to make a roster around here since DuJuan Harris went from the used car lot to the starting backfield.

The fact of the matter is Aaron Rodgers just missed him.

On third and goal at the 2 Walker lined up as the No. 4 receiver put a move on safety Yeremiah Bell and broke to the sideline running 2 yards deep in the end zone. Rodgers rolled a little to the right and threw incomplete to Jermichael Finley ending Walker's moment.

"I was open" Walker said after the game. "He (Rodgers) even asked me 'You were in?' Yeah I was open. No. 1 he threw to Jermichael but I was open. I was hungry for that one. My eyes got big."

Rodgers should be used to Walker being open. He's been open a lot during the first two weeks of training camp and the times he hasn't he's made it a 50-50 proposition by fighting for every ball thrown his way.

In practice Monday Walker was the No. 3 receiver behind James Jones and Jarrett Boykin a reward for his five-catch 41-yard performance in a 17-0 loss against the Arizona Cardinals Friday night. Walker caught all but one of the passes thrown to him in leading the team in receptions and had the second-longest play of the game with a 22-yard catch and run.

"I couldn't have dreamed it up that way" he said of his first game.

Walker's ascension is as close to a Halley's Comet event as you'll find.

He was recruited by just two mid-major colleges (after breaking Indiana's high school record for receiving yards) was completely passed over in the NFL draft (despite setting four school receiving records at Illinois State) and had to try out with 26 other guys for a couple of remaining spots on the roster just to get a ticket to training camp.

Now he's taking snaps at the No. 1 slot position?

"It just shows that somebody noticed me" Walker said after practice Monday. "I took the reps and it surprised me. But I had to act like I knew it was coming all along. I just took it in stride."

Coach Mike McCarthy said it is that point in camp when players who carry strong practice capital and double down on it in preseason games get the chance to move up the depth chart. And so Walker who began building his portfolio during his rookie orientation camp tryout in May is getting to show what he can do with the starters.
