absorbing man vs green lantern

Who will win between absorbing man and green lantern?

Lantern could probably trap him in his ring.

Can he absorb a light construct

Yes. Creel has easily absorbed one of the most powerful objects in existence, so GL energy wouldn't be hard.

Can Creel even read?

No he cannot read, that is prepostorous. (how ever you spell it, im feeling lazy today)
If he absorbs the will power contruct he's either getting shattered or absorbed by the ring, thats just stupid thing to do, best thing to do best thing he can do is avoid the energy contructs, cos then hes ****ed,
