Laver, maybe, put dread into top player (7)
I believe the answer is:
seaweed
'laver maybe' is the definition.
(type of seaweed)
'dread into top player' is the wordplay.
'dread' becomes 'awe' (I've seen this before).
'into' indicates putting letters inside.
'top player' becomes 'seed' (eg a seeded tennis player).
'awe' inserted into 'seed' is 'SEAWEED'.
'put' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for seaweed that I've seen before include "What's seen at the coast" , "Main plant" , "Marine plant" , "We eased (anag)" , "Wrack" .)
