<P> Neuroscientists at Ohio State University launched baseballs from air cannons at football helmets in order to simulate a kick or blow to the head such as a tackle . It was found that the helmets could withstand 2,500 Newtons or about 562 pounds of force . </P> <P> Vijay Gupta, a professor at UCLA, has done research and produced a special polymer that if added as a layer on the inside of football helmets can produce up to a 25% decrease in the g - forces a player would experience . This reduction of forces would produce a similar amount of reduction of the probability of a player suffering a concussion from the same hits . </P> <P> In 1948, the Los Angeles Rams were the first NFL team to put logos on their helmets; the basic "ram's horn" logo on the helmet has remained mostly the same, except for color, ever since . As of 2018 the Cleveland Browns are the last remaining NFL teams not using any form of primary logo on its helmets . The Pittsburgh Steelers are the only NFL team that puts its logo on only one side of the helmet (the right side), while the Cincinnati Bengals, after using a wordmark for a helmet logo into the 1980s, use a striping pattern instead of a logo . </P>
