Chicago Cubs owner Tom Ricketts has decided to go back to his original renovation and expansion plan for Wrigley Field that could significantly affect rooftop sight lines.

The move is expected to drew legal action from the Wrigleyville rooftop owners.

Ricketts said in a video posted on the team's website that he needed to move forward with his $500 million privately funded mission to revitalize the 100-year-old ballpark and the surrounding area in order to see the fruits of the revenue generators his counterparts enjoy.

"Being unable to improve our park puts us in the hole by tens of millions of dollars a year," Ricketts said.
