Walton welcomed a player of her caliber when she moved from Great Falls, Va., prior to her junior season in 2009. With Cobb on the roster, the Lady Raiders gained a knowledgeable player whose roots came from Maryland, a hotbed for competitive lacrosse.
Cobb turned out to be a solid fit for Walton.
"Erin's strength is her field vision and ability to see options for her and everyone on the field," Walton coach Mandy Ryan said. "She expects the game to progress at a very high speed, and that comes from people who have played since elementary school.
If Cobb wasn't scoring goals for herself, she was assisting others in doing so. The senior attacker is the 2010 Marietta Daily Journal/Cobb County Girls Lacrosse Player of the Year after finishing as the second-leading scorer in the state with 86 goals. She also added 37 assists and 61 groundballs.
Cobb also helped Walton (14-7) make its first final four appearance in school history and said her coaches and teammates at Walton were supportive and encouraging.
"Words don't describe (my experience at Walton)," Cobb said. "You train with the girls day in and day out, and what you take from the season makes you who you are. You appreciate those who help you along the way."
Cobb, who will be playing club lacrosse at Georgia Tech next season, doesn't want to be remembered for being strictly a scorer for Walton. She said dishing out assists is also a huge part of her game.
"I love to score, but I love to assist more," Cobb said. "(Assisting on goals) is an honor because it's great to watch your teammates succeed."
Cobb said she might not be the fastest or the most talented player on the field. It is her composure during stressful situations that stands out, as well as getting her teammates to follow.
"Being the captains, (Cobb) and I always look to each other to calm the team down," Walton midfielder Ali Johnson said. "We both have that vibe when we play together, and that gets the team going. When either of us is calm, the plays and the goals start coming."
Cobb's highlight this season came when Walton rallied from seven goals down to beat South Forsyth 12-11 in the Class AAAAA state quarterfinals. She had five goals, with three coming during the Lady Raiders' big rally.
Other memorable moments for Cobb included eight goals in a 19-8 win over Kell. She also had four goals and four assists in a 12-11 loss to Lassiter and added five goals and four assists in an 18-4 win over Pope.
For the first time in six years, Cobb will take a break from lacrosse over the summer before she joins the Georgia Tech club in the fall, where she will likely team up with familiar Cobb County alumni such as Olivia Janus (Lassiter), Emily Amsler (Harrison) and Danielle DeLessio (Pope).
