None of the extensions need to happen right away because the minimum spending requirement runs through this upcoming season. My understanding is that they just need to hit the threshold before the end of the league year, so they can do deals with JJ, Kmet, and Mooney whenever it makes sense.
Given the way we've seen Poles operate, I'm sure there are a few scenarios in play for how he'll allocate the remaining cap space. I suspect extensions are a later part of that plan. He has a very business-like approach, and I like that we don't see him panic and spend stupidly like Pace did. He pursues an objective, doesn't overcommit, and shift gears as the situation dictates.
