Your college choice is not a 4 year decision. It’s a 40 year decision. Having a game plan – with the support to execute that plan – makes all the difference.  ~ Rex Grayner

Zack Walz

Vice President

Zack Walz, Student-Athlete ShowcaseHigh School: St. Francis HS (Mountain View, CA)

College: Dartmouth College (1998)

Degree: BA History

Before SAS: NFL Arizona Cardinals linebacker (1998-2002)


Zack was a standout linebacker at St. Francis HS in Los Altos, CA. When college coaches all but overlooked him, Zack’s dad launched an aggressive recruiting campaign. In the end, Dartmouth College came calling.

As a 4-year starter for The Big Green, Zack earned All-Ivy League honors three times and was named All-America as a senior. The Arizona Cardinals drafted Zack in the 6th round, and he enjoyed a 5-year NFL career before retiring in 2002.

Zack’s story of “overlooked HS prospect to NFL linebacker” gained national attention, and it compelled him to start a company to help prospective athletes avoid common recruiting pitfalls. It was here that he connected with Rex, and the rest, is history.

One of Zack’s closest friends was Pat Tillman, the former Arizona Cardinal who was tragically killed in combat in Afghanistan.

Zack resides in Scottsdale, AZ with his wife Eva and their children, Channing and Everly.

Upon graduating from TCU, Hailey became a member of the Dallas Cowboys Marketing and Promotions team where she worked for one season before moving to Denver, Colorado to pursue her passion for football and athletic recruiting.

I joined SAS because I have a passion for sports. I loved every day that I was able to work from the collegiate side of football recruiting and felt that it was time to work from the high school side to help young athletes turn their dreams into a reality.

Degrees Earned: BA Human Biology, Masters in Education

Before SAS: Teacher, 3rd and 4th grades, Denver Public Schools


Erin Radigan grew up in Columbus, Ohio.  She first joined her area’s club rowing team during the winter of her freshman year of high school.  As she began to realize success at the high school level, she set her sights on rowing in college.  Erin was recruited by DI schools across the country, and enthusiastically accepted an offer to row for Stanford University.  While at Stanford, Erin was a part of the 2009 National Championship winning team.  She also won the NCAA gold medal in the 2v8+ race in 2011.  She was named a team captain during her senior year.

At Stanford, Erin earned a BA in Human Biology and an MA in Education.  She went on to teach in Denver for a number of years before she felt the call to get back into the world of athletics.  She is thrilled to be part of the Student-Athlete Showcase team, and loves being of service to the next generation of college athletes.

Competing in collegiate athletics was one of the most formative experiences of my life.  I joined SAS to make sure that every qualified athlete gets the chance to have that experience.
