Im all for getting Purke done. Im as big a fan of his as anyone on this board. However, there is a line to be drawn. He does have some mechanical issues, which seem to be at the root of the injury. He has to work on those. If he doesn't iron them out, and keeps getting hurt or becomes such a headcase constantly messing with his mechanics is a real possibility.
I get that there are different break downs on how the contract works out in terms of a major league deal and just a signing bonus. Im fine putting in work and going in the $4mill range. That doesn't mean you go get him at all cost. That doesn't mean you go to $6-7mill to get it done. If they do, Ill be happy. Its not my money and I want him to be a National. But, it's totally understandable if they don't go that high to get it done. He does bring some risk to the equation.
