How will Smith and Williams fit into the CFL? Will they dominate the League? I suspect NFL fans figure that Williams and Smith will tear the League up and instantly bring their teams to greatness, but I doubt that will be the case. Frankly, it would be nice for the CFL and all of its supporters if Williams and Smith are only average up here. That would be ammo against the argument that the CFL has only second-class players (which we don't). The CFL and NFL are different games, and it would be a neat proof that there is top-level talent in this League if Smith and Williams weren't any more dominant than they were in the NFL.
Personally, I don't think they will dominate the CFL any more than they did the NFL. I certainly hope they don't. They won't be able to find it easy, and they'll have to adjust to the new game. It will be interesting to see how they do up here ... (assuming Williams does come up here).
