College Football National Champion vs average cfl team - who wins?

Let’s say they play one half under each set of rules. The CFP will likely have more NFL players, and most likely better training facilities and coaching, but the CFL team will be entirely composed of players who were good enough to play after college, and have the advantage of full physical development

For context on the level of play in the CFL vs NFL: this year’s CFL mvp played extremely well in the CFL so a few years ago he tried out the NFL, was cut by three teams, and then went back and won the CFL mvp
