After playing for the Box Hill Hawks in 2002,[3] Angwin was drafted by Carlton at pick 17 in the 2003 Rookie draft[4] and he made his AFL debut in round 14, 2003. By the end of the 2003 season, Angwin was considered to be a future star at Carlton.[5] However, continuing off-field problems, including charges being laid against him from stealing from teammate Karl Norman, meant he remained a controversial player.[1]
Early in the 2004 season, after Carlton's round 2 win against Geelong, it was claimed that Angwin and Norman arrived at a Carlton training session under the influence of ecstasy.[1] While Norman admitted to taking the drug, Angwin denied it but a subsequent drug test proved positive and Angwin was sacked by Carlton.[6]
