White is well on the way to doing that. He has been impressive ever since he stepped on the field for offseason workouts and has earned the praise from coaches and teammates.
"The type of person he is; he motivates himself," said wide receivers coach Adam Henry. "He has a little chip on his shoulder, and he bring it to the building each and every day."
White arrived at Alabama as one of the premier wide receiver prospects in the nation. He started over ballyhooed freshman Amari Cooper until a season-ending ACL injury impeded his progress. Cooper than starred while White faded into the background. The latter served as a starter last season, but managed just 40 catches for 504 yards.
He is now out to prove that the potential with which he arrived at Alabama will not go unfulfilled.
"I'm a hard-worker and ultra-competitive," he said. "I just can't wait for the opportunity to showcase my talent. I know what I want to achieve, and I know that I need to get better than what I've been doing. ... The NFL is not for everybody, but I feel like I'm at home; I feel like I belong here. I know I'm going to succeed. This is just the beginning."
Martin plays tackle and guard. He spent part of last season on the 49ers practice squad, but the team said there were too many similar players at his position.
Chryst, who is stepping in for his first year as the offensive coordinator, says he's seen a lot of progress with Kaepernick on the field and that's boosting his confidence.
"He's playing with a lot of confidence," Chryst said, per the team. "I think he's having fun playing football. I think it's awful important to him, so how do you catch the right balance between, I'm serious here and it's still great to be with my teammates?"
Kaepernick has adopted the leader role for the 49ers, which is a crucial part of his development, according to Chryst.
"There's a serious side to Colin about working hard," Chryst said. "There's a side where he'll get on people if we're not operating, and then there's that side where you feel confidence and you see within his demeanor - that's a positive."
Kaepernick passed for 3,369 yards and 19 touchdowns last season.
The 24-year-old was waived by the Jets on Thursday.
Smith is on the short list for defensive MVP for the team's offseason program. He used this offseason as an opportunity to get into better shape and to make sure he's ready for the season.
“Really just getting into the optimal shape I want to be in,” Smith said. “I want to come in and make sure I’m ready to go.”
The strong offseason performance comes on the heels of a 2014 season in which Smith posted a career-low two sacks in seven games of action.
“I don’t think I played to my level, and I want to do everything it takes to play consistently at my level,” Smith said. “I know that when I’m playing consistently and I’m on my game, I can’t be stopped.”
