Depenps a lot on the player. Jason Garrison or Cody McLeod are easy, because the number of their collectors are really limited, but I can guarantee to you that if you want to try the same with Crosby, Matthews or McDavid, you are facing a lot tougher challenge. If you don't believe, offer a Garrison for Crosby and then offer McDavid for McLeod and analyze the success rate.
