The whole discussion revolves around 2 things;
1. Does your league count Ks?
2. Do you have a strong average team?
If your league counts Ks you can't afford Wilkerson, conversation over.
If not and you have a strong enough average to eat his potential .250 average for the year, he is a must have. He will score 110+ runs, hit 25-35 HRs and a decent RBI total. He also qualifies at 1B, LF, CF and RF if your league has those spots. He's a scoring machine with good power that backs up 4 spots, can't beat that with a stick.
