Injuries

Hi I am currently 3-3 in a 14 man Points league on ESPN. I had the second pick in the draft and (stupidly) chose Wemby instead of Shai hoping that he would be able to make the leap to superstar. And he has, but also got injured in the process. I have made some very stupid trades, resulting in me losing Deni Avdija and only gaining back a pitiful Jarrett Allen that is also injured. I am tanking until Wemby, Castle, And Allen gets back but I am still worried. Jamal Murray is carrying my team, which is definitely a bad sign and most of my team right now are averaging points in the thirties and mid thirties. Most of my team are waiver guys at this point and not any good waiver guys. Should I try to trade wemby for depth? I really don’t want to become last in a league where I had the second pick…
