I actually keep forgetting about Collins. Now that I think about it....they won't touch a 1 tech. They are going to rely on Collins for that. Unless they plan on putting Irving on the outside and moving Collins to 3 tech.
Obviously, since they love position flex, it will depend on who they feel fits best, but I would think the plan is for Irving to be the starting 3-tech, Collins the starting 1-tech and Lawrence and Charlton the starting ends.
I know fans see Collins as a better 3-tech than 1-tech, but he really wasn't disruptive in the 3-tech role last year before Irving took it over and adjusted well to playing 1-tech once Dallas figured out how to better use his strengths at that position. Some also are just stuck on the idea of having a big body at the 1-tech spot, when Marinelli has shown that size isn't really his preference.
If someone signs Irving, though, I could see us moving Collins back to 3-tech because filling the 1-tech role will be cheaper. However, because the 3-tech role is so vital to this defense, I could see us using an early pick on the position and keeping Collins at the 1-tech.
Again, I'm not saying I like this, only that I think it's a realistic interpretation of what this front office will do.
