I agree but I think that in reality it means they'll get in.
Also, of the three bands you mentioned only Nickelback has exceptional album sales for a big name band. If the HOF went by sales alone, ignoring all other criteria, and inducted the same number of bands they do already, then Maroon 5 and Imagine Dragons would never get in based on their current sales numbers.
Nickelback is getting in unless all their fans O.D. on meth before their nomination comes up. Otherwise they're too successful not to.
