Two things I see about this though...
1. I don't think he's reflecting ET's number in there, so available cap space would actually be ~$2.4M when factoring that in.
2. This includes the tender we've made to Justin Houston. Very few other sites I've seen are including this. If he were to sign elsewhere in the next like 3 weeks or whatever it is, we would gain another ~$2.3M.
So effectively you have ~$4.7M in cap today, with about half of that earmarked for Houston.
Basically anybody we sign next will require some kind of contract restructure/extension to do it, and we'll need to do at least that by early September anyway to fill out the roster and have cap space to play with in the season.
