Half-Sack's Forgotten Skill In Sons Of Anarchy

In one get-rich-quick scheme in Season 1, Episode 7 ("Old Bones"), SAMCRO attempts to put Half-Sack's history of boxing in the military to good use. After setting up a bare-knuckle boxing match, Tig (Kim Coates) and Chibs (Tommy Flanagan) tell him to throw the fight. Because the club has bet against him, Tig and Chibs want to reap the profits from Half-Sack's loss. However, this plan fails pretty specularly when Half-Sack opts not to take the dive (via YouTube). 

Unfortunately, Half-Sack is distracted during his fight at the exact inopportune moment, when he notices Clay Morrow (Ron Perlman) share an affectionate moment with Cherry (Taryn Manning). Flying into a jealous rage, Half-Sack does the opposite of what is intended and almost kills his opponent. In the grand scheme of things, this plotline results in relatively low stakes. Even though he doesn't throw the fight, the club still makes off with a decent amount of cash. This may point to the reason why his skills as a boxer are never brought up again. Although the scheme is profitable, the amount of effort involved in the operation may not have been worth it to the club. Of course, the other reason this skill was likely never revisited is that the focus wasn't ever really about boxing. It was about Half-Sack and Cherry.

Half-Sack's jealousy proves that he is serious about making Cherry his old lady, despite her previous dalliance with Clay. This ultimately proves to be a defining moment for the relationship, proving Half-Sack's feelings are genuine. If not for Half-Sack's death and the tragic, real-life death of actor Johnny Lewis (via The Hollywood Reporter), it is at least possible that this relationship and Half-Sack's boxing career could have returned.
