The "discount aisle" comment tells me that people are still scarred by the Ollie experience. Plenty of teams took big leaps this year by shopping at the same discount aisle. If he can't get anyone, or the guys he does get are terrible, I'll be the first to say it's starting to fall apart.
The portal is two bins. It used to mostly just be the 1 (except for rare cases when a coach got promoted or whatever), because strong players usually didn't want to sit out. But now it is a "Discount Bin" and a "Now Featuring" bin.
There are players too good or too bad for their level. It works both ways. Our program is in a good spot, so we get to shop at the Now Featuring bin. This bin has guys that worked out the rawness at a lower level and now have a complete game. Or who prove the doubters about their size or skill level wrong and have proven to be capable players. There's also the guys whose coach left and were already high major in there.
Diggins and Gaffney are both in the discount bin, but Diggins will likely get a high major team to take the chance and shop in there for him.
