Only bad things would happen if you do, Linear coaches for the most part are dictators.
Balls in the air... are much more productive. And if balls in the air included HR, line drives, and pop outs, they have a much bigger average than ground balls.
According to THT, the MLB average groundball out rate was 74 percent in 2007 and 2008. By comparison, the MLB average flyball out rate was 83 percent in 2007 and 84 percent in 2008. Another way of looking at those percentages is to say that batters hit about .260 on groundballs and .160-.170 on outfield flyballs (excluding home runs).
The line drive out rate was 29 percent in 2008, meaning batters hit roughly .710 on these batted balls. The hit rate on infield flies is nearly non-existent as pop-ups are converted into outs 99 percent of the time.
When it comes to batting average, line drives are king, followed by groundballs, outfield flyballs, and infield flies. Put it all together and National and American League teams hit .298 and .302, respectively, on balls in play in 2008. NL and AL clubs had BABIP of .301 and .305 in 2007.
However, when it comes to production, flyballs are more valuable than groundballs. To wit, including home runs, line drives produced .40 runs in 2007 and .39 in 2008, while the average outfield flyball yielded .18 runs in 2007 and 2008. Meanwhile, the average groundball generated .05 runs per event in 2007 and .04 in 2008.
but... if you insist, I suggest you send him this...Babe Ruth.
