I had Myles Turner last season his season started the same way, how can you not get better as a player? this dude is such trash. I'm in a 12 team league and wish I had gone with someone else.
I picked Isaac and Myles, also picked up Levert and drafted K Love...
I have Love and cannot trade him away for a half-eaten burrito right now, so I commiserate with your plight. You will need to work the wire hard this season if you want to turn around a busted draft. It's been done. Just be patient and vigilant.
I'm finding that Myles has some value beyond his poor rank. Treat him as a blocks specialist that doesn't kill percentages and work around that. (for instance, I have JaVale on that same team and am clobbering in blocks).
