Can someone explain to me the Cubs and Josh Hamilton Rule 5 Draft?

Question

I'm not too sure on Rule 5 drafts, wasn't it out of control of the Cubs?

Answer 1

the cubs didnt want josh hamilton to come up to the majors

and they waited to long so the reds picked him up, than they traded him to the rangers

when somebody isnt up in the majors, in the minors, for too long than another team can sign him
