Because these look identical to our white and blue practice jerseys, neither of which look anything like game day jerseys. Gameday jerseys will be the tight fitting Adidas pro-knit material, and have stitched emblems and numbers. And the numbers on the navy jerseys actually did have an outline, it was just the navy stitched piping around the gold number. They wanted to use the gold number to showcase our custom "yellow jacket pattern" in the numbers. That pattern won't translate on a white number. They probably could've used some white trim on the stinger stripes or logos, but those jerseys were originally introduced to wear with white pants, so they may not have thought about needing more white on them.
