I have very mixed feelings on this.
On the positive
I love the cheap extension and if the minor league coaches and front office have that much belief in the work ethic, character, and baseball potential I trust this. He is a gold glove caliber defender and especially given how far out the contract goes the value should be OK even if the bat isn't special. He doesn't strikout much and takes walks and anyone who has followed the Brewers system knows there will likely be 20+ HR potential in the bat. He was only 20 last year in AA, had he played A+ last year and hit like .280-.300 people would be way higher on his offense. On top of that, I wont complain when the org actually decides to spend money. I dont think this money will be a factor in extending Made or other prospects in the next couple years.
On the negative, I think we could have waited until the end of the year (or midseason) and signed the same deal. That would have given everyone a little better look at the bat and his future. I think a Turang extension has probably passed but I would probably have rather signed Sal, Patrick, Uribe to an extension 1st. Since we will be paying him probably like 10+ million the couple years before the options there is a lot of risk that he wont reach his potential and paying him that money could cost us an impact players down the road.
Overall, I like this more than it worries me. However, I dont get why we just didnt wait a couple months and have a little better idea what the offense looks like.
