There upside is probably similar, but Bartschi is a far safer bet to reach that potential, and in the event neither reaches their upside, Bartschi is also a safer bet to still be an excellent roll player. Much better motor, amongst other things. Bartschi would have no problem fitting in on an elite third line. Jensen, not likely.
So safer bet to reach his upside, and much less risk to him even if he doesn't.
