If you watched any professional sports on St. Patrick’s Day, you may have noticed some of the teams wearing green uniforms. This is a tradition that dates back to the seventies, according to Paul Lukas of UniWatch in an article he wrote for ESPN online. If you ever need to know anything about the history of sports uniforms, UniWatch is the place to check first. I really enjoy learning something new every time I read his blog. The trend of alternate jerseys is something to keep in mind when you are selling to teams. It’s a great way to increase your team sales.
