Angell started out his career calling high school football and baseball games in Jacksonville, North Carolina in 1999. Angell's first job with the Tar Heel Sports Network was calling play-by-play for a Little League Baseball game for WIZS while still an intern. John Rose, who was the engineer for the Tar Heel Sports Network at the time, is part of the family who owns WIZS. Angell continued to call high school football games while still an undergraduate at UNC Chapel Hill. He also started doing color commentary for North Carolina Tar Heels women's soccer and women's basketball. After graduating from UNC Chapel Hill, Angell worked in various radio and hosting positions within the Tar Heel Sports Network. Prior to becoming the voice of the Tar Heels, Angell was best known for providing color and later play-by-play commentary for Tar Heel baseball from 2000 to 2011, and for working alongside Durham and his staff as a host and color analyst for football and men's basketball broadcasts from 2005 until 2011. As assistant director of new media at UNC Chapel Hill, Angell produced many features that have been shown on the video boards at Kenan Stadium and the Dean Smith Center.
Angell feels this call sparked his relationship with the Tar Heel fanbase and says people still talk to him about this particular call. Angell even parodied this call for a video for The Daily Tar Heel’s sports department. When the 2016-17 basketball team won the school's sixth NCAA title, Angell ended the game by saying: His use of "dadgum" was a nod to basketball coach Roy Williams' frequent use of the word. Angell called part of the 2014 Tar Heel baseball season for ESPN3 and WatchESPN. Angell also wrote articles for the now-defunct magazines Tar Heel Monthly and CAROLINA: the Magazine, as well as for GoHeels.com. Angell co-hosts a podcast, Carolina Insider, that launched on September 20, 2016, in a partnership with Learfield Communications and podcast provider DGital Media. Angell's co-host is his longtime friend, Adam Lucas. Lucas is a longtime TarHeelBlue.com and GoHeels.com columnist, an author of Tar Heel men's basketball books, and a contributor to Tar Heel Sports Network broadcasts. Angell worked with Lucas, who provided color commentary, on Tar Heel Sports Network coverage of Tar Heel baseball as early as 2004. Learfield offered Angell the podcast by himself, but Angell asked Learfield if Lucas could co-host the podcast with him. Both Angell and Lucas were considering working on a podcast together prior to Learfield's offer.
