If Bloodman had no Magic, don't you think Gajeel would've said something along the lines off: "What the hell? I'm not sensing any Magic from this guy!"

He noticed Magic and he didn't even state that the Magic was weak, just that it was weaker than the Magic of the other Spriggan Shields. Likely, Bloodman had an amount of Magic power which puts an average mage to shame.
