I think it's a combination of the bats, the ballpark, and having a lot of young players.
We were going to lose a lot of power regardless of what kind of bats that we're using.
Is it concerning? To a degree. Home runs don't necessarily = good hitting team. Home runs = good power hitting team. I remember the Detriot Tigers in 1991 had a lot of power hitters like Cecil Fielder, Rob Deer, Mickey Tettleton, and Pete Incaviglia. They hit a ton of home runs, but they also struck out a lot to. They had some high home run totals, but some guys with some fairly pedestrian batting averages.
State's team next year is going to be all about speed and creating runs. Like the Cardinals in the 1980's under Whitey Herzog. You can win doing this, and have an offense that is actually pretty good. I know the Cardinals in 1985 only had two guys that hit more than 10 home runs in Jack Clark and Andy Van Slyke and maybe Darrell Porter, but they also had a ton of guys that had high averages and even more stolen bases.
I will say this though- the lack of power is concerning because in an ideal world you would like to have a lineup that can do both- at least I would on a note of personal preferance. If we get into a slugfest, it's going to be hard for us to win. People can sugarcoat that with bats, the ballpark, and etc. but I do think that it is a concern.
I will also say this in regards to power with the current MSU players- power is something that is usually developed over time and one of the last things to "come" to a player. That's why I made note of the fact that we have a lot of young players as a factor in our lack of power. But, I do think that some players such as Hunter Renfroe, Wes Rea, Daryl Norris, and maybe even DeMarcus Henderson will develop power over time. But as of now, they are freshmen trying to adjust to the college game, and in Rea's case, he is trying to get healthy. And when they develop that power, I think we will have a much more balanced lineup because we should also still have guys like CT Bradford and Adam Frazier that are more speed guys.
