CLEMSON -- Clemson kicker Chandler Catanzaro sought someone to help him clear the psychological hurdles of the position after struggling in high-pressure environments last season. After some research, Catanzaro's father found the ultimate summer coach for his son: one of the NFL's all-time great kickers, Morten Andersen, was willing to help.

Catanzaro believes the offseason sessions with Andersen are paying off as the sophomore has converted 84 percent of his field goal attempts in camp and will likely enter the season as Clemson's placekicker. Catanzaro is ahead of freshman Ammon Lakip on the depth chart.

While Andersen worked with Catanzaro on his kicking mechanics much of the work was dedicated to the psychology of the game. Catanzaro missed pivotal kicks in tough environments at Auburn, at Boston College and at Florida State last season. Catanzaro made 14 of 22 kicks overall last season.

"We worked mostly on the mental stuff," Catanzaro said, "how many balls you kick in the net on the sideline, when to have your helmet on ready to go, stuff like that ... mostly visualization stuff."

It is the kind of help Catanzaro cannot find at Clemson as like most programs the Tigers do not employ a coach who specializes in working with kickers.

"(Kickers) kind of have their own tribe," Clemson coach Dabo Swinney said. "They go all over the place in the summer time that's just the way it is."

Catanzaro said he has also added strength, increasing his range by five yards.

Catanzaro also has more confidence in his field goal unit. Last season, Clemson replaced long snappers going from Matt Skinner -- who double clutched the snap on the game-tying field goal at Auburn -- to Phillip Fajgenbaum.

Bellamy returns

Freshman running back Mike Bellamy returned to practice on Monday. The five-star rated back missed nearly a week of practice after jamming his shoulder. Bellamy is lightning quick and has 4.3 second speed in the 40-yard dash but his slight 5-11, 185-pound frame brings his durability into question.

Extra points

Swinney is disappointed with the play of the second-team offensive line this camp a group that includes former highly-rated recruits Brandon Thomas and Kalon Davis. "Some of them are there by default. I'm pretty disappointed in some of those guys," Swinney said, "in their preparation and overall commitment." ... Sammy Watkins was held out of practice Monday with a hip flexor. Watkins missed Saturday's scrimmage but the injury is not thought to be serious.
