Lambert suffered a stress fracture in his left leg in March, so getting back to 100-percent and hitting the road to throw in front of college offensive coordinators was a must.
While he remained sidelined throughout June, Lambert returned to action earlier this month, joining his parents for camp stops at – in order - Arkansas, LSU, Alabama, Tennessee, Florida State, and Florida.
Lambert and his father, Drexel Lambert, arrived in Baton Rouge on the first day of the Les Miles Camp, and, at the request of offensive coordinator Steve Kragthorpe, pushed their stay beyond the anticipated timeline.
"We had planned on staying the half day on Sunday, but (Kragthorpe) asked us to come back and work the next day," Drexel said. "I thought it went well."
While the Tigers have yet to take a commitment from a quarterback in the 2012 class, the dominos nationally are already beginning to fall.
Jameis Winston, the nation's No. 2-ranked quarterback prospect, is set to announce his decision before the end of the month, and the Hueytown, Ala., two-sport start has narrowed his list to Alabama, Florida State, and LSU.
"(The LSU coaches have) got a couple guys they are waiting on before they make any more moves," Drexel said. "They've been honest with us and said where they stood."
While he didn't earn a scholarship offer while in Baton Rouge, Lambert, a four-star prospect and the nation's No. 7-ranked quarterback, is still in the chase for one of LSU's quarterback spots.
"I talked to Coach Kragthorpe (on Thursday)," Lambert said. "We talked about what I am doing and what he has been doing. He told me to stay in touch, so I'll get back with him early next week.
"I feel like I did pretty good over at camp. Obviously I want to make every throw and I didn't do that, so I'm a little hard on myself. But overall I was pleased. Coach Kragthorpe said I did a good job and he appreciated me coming, and we're going to keep talking going forward."
What were the Lamberts' impressions after a pair of camp days in Baton Rouge?
"We really loved it," Greyson said. "The facilities were definitely top-notch. All the football complexes and practice fields are right there together in the same spot, and I liked that. We got to work out with Coach Kragthorpe at their indoor practice field, and it is really nice.
"I had a lot of fun while I was down there."
With scholarship offers from Alabama, Boston College, Clemson, Georgia, Louisville, Miami, Mississippi State, North Carolina State, and Virginia, Lambert will make one final unofficial visit before he turns his focus to fall camp at Wayne County High.
"I am leaving Friday, and on Saturday I will be visiting Virginia," Greyson said. "After I visit there I should have a much better feel for everybody."
After Winston, the nation's top uncommitted quarterback prospect is Old Tappan, N.J., four-star Devin Fuller – who has yet to decide if he will play under center or move to defensive back in college.
"Because of some of the recent commitments I feel like some schools are changing their stances and looking at different guys," Greyson said. "So I haven't done any narrowing down, and everyone is still in the mix."
