I voted no.
One top line starter won't turn this season around in two months.
Now if Ben does have an opportunity to snag a top guy that he would have targeted in the off season then fine. I just don't see the necessity of a paying top prospect prices to make it look like he is trying to salvage this mess of a season.
I think the abundance of good arms entering FA should be his focus. I say that we need two as things stand now. That could change if Johnson performs well.
But again, if someone is about to be moved that Ben has a boner for, he should consider some kind of move.
Other than Swilhart I say any player currently in the Minors is expendable.
