Harrison Barnes to me feels like the ideal target right now, and a realistic one. He's still just 28 years old (so it's not like he's some 35-year old veteran who is limited). Got size at 6'8", and so far this season is averaging 17/6 on 50% shooting and 41% from behind the arc.
Last night against us, while he didn't shoot as well (I think 7-18), he gave the Kings 24/6/5 and made an impact. He would be a great 3rd or 4th option on this team and give the Jays some help. Gives the team another playmaker too and a little Kemba insurance.
