He's going to be better dude, don't even worry about that, its not even in question imo... there is a good reason why cassel never started for anyone until he got here, and theres a good reason why Smythe has.

How much better he is remains to be seen, while i believe their arms to be roughly similar, everything else about Smythe is better... more athletic and more instinctual, most stats bear that out and the ones that don't have some fairly strong caveats that need to be attached.

I fully expect far better play than we ever got from cassel.
