Kicking is an area where Canadian College and Junior players have a distinct advantage over NCAA players ... the simple truth is we kick much, much more with 3-down rules and our kickers are often at least as good, if not better, than NCAA prospects.
There are situations where there just isn't a good kicker available in CIS or free agency and a team needs someone to play that position. Often that's because the guys with CIS experience are playing in the NFL, where they are generally highly regarded.
In that case, you really don't have much choice than to waste an import roster spot on an NCAA player ... and it doesn't hurt to remind yourself, while you do, that you're taking a player the NFL didn't want in exchange for a CIS player they do want.
But, at best, it's a short term solution, and the team should find a Non-Import as soon as practical to get the ratio where it needs to be.
