Playing Canario may not work. Maybe it will make them worse. Maybe he hits over 100 wrc+. We don't know. What we do know is that this team sucks and is losing as its currently constructed, this offense is broken, they have no slug, they're not hitting HR, they're leaving lots of guys on base, and the bottom of the order is among the very worst in the MLB in hitting.
In Canario's short stint this year he registered the 3rd highest average bat speed in the MLB, that's above Morel, he has excellent power, potentially elite. Maybe he's terrible, maybe he goes on a Morel/Wisdom tear when they were called up. The risk of trying Canario is zero, they need to act with urgency and take risks. The Cubs continuing with the same lineup and roster is a losing idea.
