However, that strength doesn't seem to be 16 players deep, meaning the Sounders might have to move up or hope to strike gold late.
Here's some of what Henderson had to so today about the coming draft.
"From this year’s class I would say the strengths are probably in the back, in the defensive positions. And then secondary, there’s a few attacking options as well. But I would say the top of the class is probably in the centerback position. But then there’s a bit of a drop-off after probably four or five guys who kind of stood out more than the others.
Never miss a local story.
"For us, those are positions we’re looking at: adding something to our defensive line is something we’re looking at. But the conversation is, at our numbers – at 16 and 35 – are you looking for the best player or are you looking for positional fit? So, depending what’s on the board."
If it sounds like the Sounders might have to move up in the draft to get a player who can contribute this season, well, apparently they're considering that.
"Yeah, we’ve had several discussions with teams," Henderson said. "We’ve weighed all the options. All of it could be possibly who’s there with the teams we’re talking to, and whether it’s the top five picks, I think, is where you’d have to move to. We’ll have some changes in our roster. We want to make sure that we keep some cohesion with the group. There’s a lot of things we’ve been weighing in to that decision. I still think we can get a guy at the 16th pick – a guy who can battle to make the 18 roster every week."
