Terrell Walden is one of them.
He has not participated in the spring due to suffering a torn ACL in his left knee last December.
It was his second torn ACL in his three-year career at Miami. He suffered a torn ACL in his right knee in May 2004.
Since he has already been through the rehab process before it "helps a whole lot" to have something to compare to and know what it takes to get back on the field.
"I feel real good right now," Walden said. "I am a little bit ahead of where I am supposed to be. At three months with this injury I am way ahead of where I was last time. The process with this leg feels a lot faster and it's a lot stronger."
Right now he is doing everything in regards to running including forwards, backwards, and lateral. Although he is coming along well, he is just taking his time with it.
Although he isn't able to practice he is able to watch and observe the new offensive scheme and philosophy of offensive coordinator, Rich Olson.
And Walden likes what he sees from Olson.
"It has been good this spring. I have been learning everything and all of the things they are putting in seem to be working," Walden said. "I am happy because it looks like I can be a part of the offense this year so I am just waiting to get back to do my part."
Walden caught two passes for 17 yards as a sophomore in 2005 while playing in 10 games.
Always known for having great speed, he believes his speed along with the rest of the receivers' talent will be showcased in the 2006 season.
"One thing I like that he (Olson) is doing is that he gives a lot of opportunities to get the ball in the receivers hands with quick passes and he likes to take a toss down the field," said Walden. "If we are in a one-on-one chance, he likes us and is going to give us a shot at it."
After two knee injuries Walden doesn't believe he has lost his speed, which is imporant for the 5-foot-10, now 170-pound receiver.
The former cornerback doesn't even think about playing on the defensive side of the ball.
"I feel like a receiver now," said Walden.
Walden expects to be partcipating in fall practices and would like to continue to add weight only if he can maintain his speed.
"I am happy just thinking about the fall. I just can't wait to get there."
