i believe i would be indetermined to, with that player.
That he is 18 is a big plus, three star potential isn't bad or really good. So gambling could lead to a better play, but they are also weaker combination.
Considering the late draft position of your team, i would be happy to still get him and put him at spot number one because better 5 star player are most likely to get picked from the team in front of you and the chanche is low to get something better then him.
