Who is this "someone"??? Do you have any proof whatsoever? If you expect to make some sort of bold claim like this, you better be ready to back it up. Until then, I think you're full of .
There's plenty of quotes and pictures showing Finley fully supporting Dirk. Never an iota of jealousy. I can post them all day long if necessary.
And, even though I don't believe it for one second, supposing there even was some jealousy, Finley would NEVER publicly show it because he cared first and foremost about the TEAM. Another reason why it's so horrible and embarrassing that some Mavs fans want to try and cheapen the accomplishments of one of the classiest men to ever be a part of this team.
