The Bears' official website lists Williams weight at 226 pounds, so a drop of 10-15 pounds would put him between 210-215. He is roughly in line with his weight from the 2024 NFL scouting combine when he tipped the scales at 214 pounds. Per Mockdraftable, Williams' combine weight ranked in the 26th percentile among quarterbacks. ESPN's Mike Tannenbaum noted in November 2025 the average weight for an NFL quarterback was 222 pounds. Last season was a learning process for Williams in his first season playing in head coach Ben Johnson's system.
