It has only been 7 months since the 2008 draft and a fair evaluation probably cannot be made for at least 2-3 years but given the strong debut of Brett Wallace I think its fair to at least address the decision to select Jermile Weeks over Brett Wallace. 

Potential Rationale:

1) The A's may have been trying to address a particular position of weakness in their minor league system.

2) The A's also may have wanted to pick someone that they knew they could sign. Though Wallace wasn't someone who had outrageous demands. 

Is that sufficient rationale to over look a much higher upside? 

Cons to selecting Brett Wallace:

1) His position is a question mark. Currently he plays 3rd base, but its unclear how long he will stick there

2) The A's have a couple of guys with similar skill sets and question marks. A pretty clear example is Chris Carter.

Reality:

Brett Wallace may make his debut in the Majors in the upcoming season. He looks like he will be well above average hitter. 

Was this move a mistake?
