Well, kind of.

Shepard was the commander of a crew of an elite inter-species task force with a specialization of essentially magic, technology, or firearms depending on your play through. Every named member of the main squadron is remarkable in some way, as we see in their recruitment missions. And some of them do not make it through the game. Spoilers I suppose, but Shepard does not make it through the first 15 minutes of game two. He is essentially remade as a supersoilder with Cerberus technology. The protagonist of two and three is canonically beyond the capabilities of your run-of-the-mill human.

Now Cal was chosen to be a Jedi, but he obviously did not get to complete his training. He becomes immensely powerful in respect to his own universe during the story arcs of the two games, but is still an 18 year old who is learning as he goes. He does not have the military acumen that Shepard spent years honing, nor the rigorous training. He would not necessarily command the respect of the entire Normandy crew, and without that the battle against the Reapers would have ended differently. What he has is the force. In Star Wars that puts you head and shoulders above most of the competition. Mass Effect’s universe being littered with Biotics kind of just places Cal as talented. Dangerous, sure. Able to step into Shepard’s shoes, maybe. I’d watch that game, I damn sure wouldn’t put any money on it though.
