I was actually just thinking about starting a lineup thread, so good work!
The big key is the loss of Schreiber and Wilkening obviously. While i'm not super close with the baseball staff, I am able to interact with them a bit. If anyone has ever seen the movie 'Moneyball', the scene where Billy Bean is just yelling at his scouts "Everyone is trying to replace Giambi and Damon, i'm telling you, we can't do it." They go on to try and equal their output with 3 other players instead of 2 studs. That reminds me of this year a bit. While I would take Schreiber and Wilkening back in an instant over what i'm going to say, it could work out better for us. It sounds like last year, opposing teams just had to worry about these 2 guys. Erstad is thinking this year, there won't be as much to "pitch around" from top to bottom. So while we lose 27 HRs, with two guys, we may be able to get there with 5 or 6 guys, which could lead to a better lineup.
Outfield
Hagge returns and most likely will leadoff, Hallmark most likely will play center and figure in middle of the lineup somewhere as he got a lot better towards the end of the season. I woudl think we are just looking for our right fielder, which could come from Palensky who had 20+ HRs in JUCO, The third guy is who we are looking for.
Infield
Altavilla is starting obviously, and Roskam is at catcher. Can Hellstrom play first? He hit over .300 last year, so you can't really take his bat out of the lineup, DH always a possibility of course. Brett Hammitt and Cam Chick are highly touted true freshmen, Hammitt actually chose us over SEC schools. Henwood is back after starting some games, but his numbers were a bit underwhelming. Can Schwellenbach play infield? I think you see him as a freshman start at 3rd base, and work towards freshman of the year honors per 'Perfect Game'. Hes that good. What about Schanaman, as he is super athletic?
I'm certainly missing some guys that could be really valuable to our team, but the good news is, our recruiting class was really good. And I can't get into the pitching because I have zero idea who they are going to start and who they are going to have coming from the bullpen. I'm anxious to see the box scores with our first few weeks of games with this tough competition. We lose a lot of firepower, but return a ton of pitching. If we make it out of February 3-5 i'm going to be pretty pumped. Four games against Oregon State are going to be really tough.
We need to finish top four in conference, we need to get a few B1G wins under our belt, and we need to get to a regional again. Hoping we can get that done. I'm willing to give Erstad a pass once every three years if he's getting first or second in conference like he has. But we can't have two duds in a row. Not with the pitching we have back. I'm buying into the hype for their 2019 team, I think we are going to be really surprised and happy with what we see from our baseball team. We will just have to deal with the early season bad record due to relying on freshmen and who we play. Once it comes conference time, we will be really good. But i'm not trying to get anyone on this train, they gotta go show people. 2018 did enough damage.
