Honestly I would dump both of them. Player A's passing is to low to be a PG and his inside skills aren't good enough for a SG. Player B has horrible passing and jump range, along with being only 6'2" so he shouldn't be played at PF. As for the 19 year old star PG, go ahead and train him, although he'll be capped out quickly, but could still be a solid player for your team. In the future, don't get anything below allstar/perennial allstar.
