I would go with Konerko. Dunn will get more hr's but imo Konerko will produce beter all around numbers for the year. The last half of last year Konerko was pretty good and it seems to have carried over to this year. He has a good Avg. so far and the power should be there as well.
There will come a day when Barry Bonds leaves baseball, and everything about the game will be the better for it.
