I don't understand why more prospective NFL quarterbacks don't go to Canada to improve their craft. The NFL finds out about the progress of players no matter where they are because scouting is so thorough.

Jeff Garcia played five seasons in the CFL, was voted Most Outstanding Player in 1997 and won a Grey Cup in 1998 before becoming an All-Pro quarterback with the San Francisco 49ers and having a pretty successful NFL career.

Doug Flutie won three Grey Cup Championships while he was in Canada and was a six-time Most Outstanding Player in the CFL before he came to the NFL and had a solid career.

Even the great Warren Moon in the late 1970s to early 1980s spent some time in Canada playing for the Edmonton Eskimos and won five consecutive Grey Cup championships before coming to the NFL and turning in a Hall-of-Fame career.

There is something to be said when a quarterback is so determined to show that he is a capable player, that they take their talents elsewhere to hone there skills, and then return to the NFL stage to have the success that they worked so hard to achieve.

Here are five quarterbacks who I feel would benefit from the CFL experience and would come back to the NFL more polished players.
