Miller really turned the corner this past spring, and before that, he wasn't really anything more than just a "good" high school player. I think he matured a lot between the seasons, but I think he's a pretty good pick-up for MSU. He hit 14 home runs, had over 100 strikeouts as a pitcher, and I think he could potentially help us out as either an OF or a pitcher, or maybe even both. That might be why he said he sucks, because before that, well, he wasn't anything that great.
Posey actually has better numbers than Luwallen- he hit .505 and hit 10 home runs, but the difference is Luwallen is a much better defensive player and has more speed. I think he would be a good get for MSU because he is a RH bat that has a chance to hit for power and can play the corner positions, both of which are major needs for MSU.
Oh, and Posey hit a home run out of Trustmark Park this past season, which I thought was quite impressive for a HS junior.
