Nashville SC and Los Angeles FC lead MLS defensive records with 13-14 clean sheets apiece through late October, followed closely by Vancouver Whitecaps and Houston Dynamo at 11-12, reflecting strong backlines, goalkeeper consistency, and low goals-against averages around 0.76-1.30 per match. With most clubs having 29-31 games played and only a few regular-season fixtures left, the race remains tight as minor shifts in final results, rest advantages, or defensive injuries could alter the outright leader. Trader consensus prices bunched near 46-50% capture this parity among multiple contenders with realistic paths to the top mark.
