If we are talking about the difference is build quality let me preface this by saying there are many Natty Pro dots that would do fine in WL, and quite a few WL dots that probably should probably be in natty pro. Those teams that make WL have a higher concentration of WL-quality dots, with quite a few teams around 100%.
Also as far a the "in crowd" comment, the thing is moreso there are a few networks that have their own farm systems and are unlikely to need to open recruit many if any dots. Then you have teams that go from 0-480 together then gut, who again never go recruiting except rarely. Then add-in that only 20% of dots on average reach decline a season, and the WL recruiting opportunities get a bit smaller still.
Also the fact is there are some WL teams that get absolutely smashed (get 0-2 wins) who are just pro teams in WL, so for the sake of our thread I assume these don't count as WL dots (the majority).
What makes a QB WL-qualityWell as far as who can get jobs, you would need to be one of the best 32 QBs at plateau in the game. Because of what's listed above you actually probably need to be better than that to get onto a WL squad. Best bet if you want your QB to play in WL (and you don't immediately find an offer), is to latch onto a dominant natty pro team you think is going to win their way in.
What makes players WL-qualityA couple things. First they need a base level of efficiency. If you are a 4-major, 3AE dot, as long as you are ~1440+ effective level, you are efficiently built enough to hang in WL. Just to be clear, this is the easier part as quite a few guides exist on basic building tactics to hit that goal np.
Then what's important is that your dot's resources are applied in a way that makes sense. Simply put, no one wants and 80 vision DT, so if you create on, he is unlikely to make a WL squad. You need to avoid bad SA's, avoid pumping undesirable attributes, and only have +% AE that makes sense. Your 30 strength 70 carrying HB probably shouldn't have a bt% piece. Your blitz LBer probably should have avoid fake%. your CB who will never force a fumble in his life should probably not have ffum%. There are so many dots out there that basically throw away tons of efficive SPs on worthless SA's or AE. That isn't to say that every SA is 100% figured out, but you still probably shouldn't pump "on the run" on your QB.
So the SA's you invest in should be supported by +% equipment. General rule of thumb is 3+ % pieces minimum, with 4 pieces normally being ideal. Also you almost always want to double-stack your most important roll (normally bb% in the front 4 of D, make tackle% on lbers, but this varies). It should be 15%+ 6% (12% reduced) = 21% minimum. If you only have 1 +% piece for a certain thing you want it to be the 5% (becomes 15%) and ideally the more +5% base the better. If you want your HB, FB, or WR to fake people out and you don't have any +% pieces, you aren't doing it right.
Lastly as general advise you want to have a goal for what your player should do, and build towards that. If the build is based on assumptions that make sense and resources are allocated towards a clear goal, you will get WL offers. One could contend I build dots wrong because I like to challenge meta assumptions (as otherwise I find building dots to be boring as hell), but I've been able to have the following dots play most of their plateau in WL or with WL offers....

http://glb.warriorgeneral.com/game/player.pl?player_id=3228565The point being a dot doesn't need to be "perfect" to get WL interest, but if the build makes sense to you it will make sense to others. Before you even start building a dot or have your first VPB run you should think about what +%'s you want, and what SA's you need for your goal.
all imo fwiw.
