I'll never make broad predictions about position players year to year, because so many at this level take big steps in one offseason.
Our 2014 team is a great example. We had a lot of guys who had done very little in 2013. Bousfield hit 0.253 with 2 HRs, Orvis 0.237 with only 3 HRs, and Allen only 0.231 with 4 HRs. They went 0.336 with 6 HRs, 0.294 with 14 HRs, and 0.339 with 7 HRs in 2014. Austin Anderson also made a decent jump moving his slugging percentage from 0.386 to 0.454 between 2013 and 2014.
Then you have Benitendi at Arkansas who went from 0.276 with 1 HR last year to 0.390 with 18 HRs this year.
Point being, if you're returning hitters, you can't project based on the previous year, because some guys do just figure it out.
We are losing a good bit on the mound though. We've got some young guys with potential, but we'll have to have a number of them step up to be really good next year.
