Agreed. Even if the home park stays the same, its profile (or reputation) might change over time. Look at the Dome, for instance. After they put up the plexiglass fence extension for the 1983 season, its dimensions stayed the same. It was even environmentally controlled so heat/cold waves and wind pattern changes would not affect it. But, as noted earlier, it appeared to be a (slight) home run hitting park in the first seven years there. It was at that time that the (forgive me moderators) idiots Tony Kubek and Bob Costas christened the Dome with the moniker "HomerDome" on national TV. That profile changed and, as noted earlier, the Dome was definitely not a home run park as it had negative numbers every year for twelve seasons, 1997-2008. What changed? The other parks in the league did. Older parks were replaced with newer, usually cozier, parks which moved the bar. Or the older ones had their fences moved in. That will happen a bit next year when Seattle's park has its fences moved in. It is, imo, a bad trend. Someone builds a small stadium or moves their fences in and, the next year, some else does too, to "keep up with the Joneses." Each time that happens, the balance of the need for speed vs power changes. Eventually, teams will have nine Adam Dunns in their lineup. I will not be watching then as I can see that at the slow-pitch softball field down the street. Oh man, how did I get on this soapbox?
