You give them way too much credit . Most people never even get the opportunity to question whether it ' s okay to procreate . It ' s an imperative . School , college , job , marriage , baby . These are just givens . It ' s hard to break out of that and question things . <| sep |> Or there ' s just more good QBs . I ' m a believer that , regardless of star vs star debates , the average athlete in any given sport is always getting better . And you really aren ' t giving NFL defences enough credit , lot of teams in playoff spots despite hot garbage on offence . <| sep |> They are made with the intention of letting you layer under them . Thus if you plan to wear a sweatshirt underneath or want it looser fitting , order it in the size you would any other shirt . If you plan on wearing it as a long sleeve shirt , size down . For reference I am 6 ' and 150 . I own a M and a S , the S fits much better but the sleeve length JUST fits .
