I think 1700 is a stretch in 4 years time. He'd still need to be averaging bout 22ppg if he played say 74 games.He's on pace to finish with 31,500 this season...
If he plays for 4 more season after this one, here's how I see it:
2013-14 = 2,000
2014-15 = 1,900
2015-16 = 1,800
2016-17 = 1,700
Thats another 7,400 + 31,500 = 38,900...
I really believe that this is on his mind for a long time now...
