Chris Rwabukamba (32) is a rare breed in the CFL: a starting Canadian cornerback.Michael Lewis' famed Moneyball is, at its core, a book about exploiting market inefficiencies, an approach that has since spread throughout sports. Similar concepts apply to the CFL, and up here, one of the prime market inefficiencies may come from the league's roster rules. Teams must dress at least 20 non-import (essentially, Canadian) players and must start at least seven of them, so there's a constant search to find top Canadian talent, but that search has often largely been concentrated for traditionally-Canadian positions such as receiver, offensive lineman, defensive tackle or safety. Because Canadian players at those positions are in such demand, it can be tough to find and keep top talent there, so there are some advantages for unconventional clubs willing to think outside the positional box. We've seen this recently with the rise of Canadian running backs like Jon Cornish and Andrew Harris, and the Edmonton Eskimos' decision Sunday to sign Hamilton defensive back Chris Rwabukamba as a free agent may suggest that Canadian cornerbacks might be the next market inefficiency, a position where teams can find quality non-import talent at a low cost.Read More »from Eskimos sign Chris Rwabukamba: can Canadian cornerbacks be a CFL Moneyball technique?
