"Great for the chase" vs "Expert in the chase"
I found these two clauses on the same page of The Iliad:
Then Menelaus son of Atreus caught the brilliant hunter Scamandrius with his sharp spear. Scamandrius was a great man for the chase, who had been taught by the goddess Artemis...
Then in a note below I read:
Scamandrius, expert in the chase, is killed by Menelaus.
What's exactly the difference between the two?
