Option 2: When Lias is contacted by the people who have designed and produced the "Flow Chart" device, and is asked to wear their new device, he happily accepts. It is a device designed to track the movement of the hair of players under their helmets, and how much hair is capable of slowing a player down. It will also tell a player which haircuts are more aerodynamic and which ones provide a better fit under their helmet. Lias doesn't usually have his hair very long, but since he has a lot of friends who like to grow their hair out pretty long, he is happy to participate and provide a sample of data for middle average hair length (if you don't have the shorter lengths to compare the longer lengths to, how will you get reliable data?) That's just how you have to do experiments. Anyway, Lias is happy to help out and he doesn't really need them to pay him because he gets paid a lot to play hockey already.
