I read a football magazine from the 80's and I saw that the majority of the WR had numbers in the 70's (Brian Kelly, Joe Poplawski, Waddell Smith). When it was changed to the traditional numbering (from 1 to 49, and 80 to 89), since I haven't seen a CFL WR to wear 70 to 79?
Also, I remember that Saskatchewwan G Roger Aldag also used #44. Also the OL used numbers lesser han 50?
