He was given a new lease this year under offensive coordinator Dirk Koetter and coach Lovie Smith has already bestowed upon him the starting gig.
Martin, who is leaner and quicker this camp, believes he can have a big season.
"The sky is the limit," Martin said, via ESPN.com. "We have a lot of potential going into this year with this team. We have a lot of weapons and a lot of guys with fire in them that want to be successful. I just can't wait to get out there with them."
The coaching staff reportedly loves Charles Sims, but OC Dirk Koetter fought to keep Martin with the team during the offseason, and he still sits atop the team's depth chart after a very strong offseason. The offense should be improved with Jameis Winston under center and a better offensive line up front. Martin is going in the 6th, so he's a good target for the “wait on RB” crowd.
