I sense a lot of booty pain from your post. Read it again, buddy.
Conor's only winnable fights at LW that could also restore some hype to his image
In other words, the top opponents whose names can help restore some hype for Conor is Poirier. Nate is a big name, but Conor beating him won't bring the hype back, because Nate just came off of a split decision lost to Conor.
Likewise, Conor can fight Eddie Alvarez, a top LW, again, but a win over Alvarez at this point does nothing to bring back the hype.
