B leaguer

Not quite A leaguer, but still pretty good in rock and metal, had some impact but lacked what was needed to make the A leaguers

Motorhead was a cool band, but career openers, they are B leaguers.

B-leaguer 

Not quite an A-leaguer, but a very good rock and metal band/musician, above 80% of all musicians. But lacks something to make the A-Leagues.

Motorhead was a cool band, but career openers, they are an example of B-leaguer.
