It's time to bring the fences in. Time to squeeze foul territory down to nothing. Overall, this ballpark makes good hitters look average. Average hitters look poor. Etc. It is not an attractive place for free agent hitters. Making the park less attractive to pitchers is fine since the plan is to grow your own pitchers and then maybe add free agent hitters when time is right. Even if a guy like Holliday liked the A's he wouldn't be very excited about being a .280/20hr hitter for years.
With limited resources we all know the A's will have a good 3 years then a real bad rebuilding 3 years . . . and on and on. At least more offense would make losing more entertaining. The Cubs at Wrigley has been a great ticket no matter how bad the team is.
On top of it all, some of the best seats in house are currently foul territory. I suppose I'm bringing this up because the A's going through one of those bad years. At least they could make it entertaining.
