Thanks for helping with mine.
Really depends what categories could propel you to first place. Howard will give you some power and RBIs, but he will hurt your average. He strikes out a ton! Personally, watching Howard every night as a Phillies fan, I think Howard is overrated and a mediocre hitter at best.
That said, I don't know a thing about Bogarts or your keeper rules (dynasty league?), so really hard to say. If you're looking to win now and you need power, probably worth making the move. However, as I look at your team, and given the QS category on top of ERA, WHIP, wins, and Ks for SPs, I could see you pushing for another SP since Strasburg won't complete the year instead. Really depends where you need help.
