Like most, I haven't been impressed with Henderson when I've watched him, but there are enough people who have watched far more than I have with a higher opinion of him. Fine with the signing, especially if it's a loan to start out.
Love the idea of keeping a homegrown player and giving him a chance in a proper setup. Whether he makes or not I have no idea, but ideally he becomes a good squad player and plays more and more because we have Conference or Europe games.
