Thug on da Line received widespread acclaim from critics. Jon Azpiri from All Music gave Thug on da Line a 4/5 rating and wrote: "After listening to Krayzie Bone on his second solo album, Thug on da Line, you get the sense that he is dealing with some personal demons. After years of personal and professional strife, Krayzie raps about his frustration with thug life in his patented singsong style on tracks like "Can't Hustle 4 Ever" and "Talk to Myself"." Evan Serpcik from Entertainment Weekly gave Thug on da Line an A- Rating and wrote: "On Thug on Da Line, Krayzie melds his precision, rapid-fire rhymes, and delicately sung choruses with expansive R&B tracks that groove like a ghettoized Neville Brothers tune. Rest assured, references to gats and thugs abound, but most often they are contextualized into tales of longing and regret."
