Sure but that's where the "7-8 schools only have over 3.5 mill" thing comes into play. We can speculate and probably correctly guess most of those: Kentucky, Arkansas, Kansas to start. I'll definitely trust an active agent with clients over an anonymous account to give me that info.
Even for centers, I can understand if the asking price is higher market-wise because they're a rare commodity. Easy supply/demand thing.
But it just wouldn't make sense if the guards we're talking about is asking for 750k. For the couple dozen (?) schools with 3 mill, that would be almost 25% of that school's budget -- which would be a almost the same proportion to a NBA max contract (25% for non-super max for younger guys, 30% and 35% for older guys with more accolades).
It also doesn't help Trilly's case that Roach basically went on twitter and laughed at the report of him asking for 1.5 mill. I think people will be surprised by guards going for cheaper than the centers, and ultimately, Trilly's being used to spread funny numbers when a lot of this stuff will feel more reasonable if any of it goes public (for example, I heard Brea's price would be closer to 500k).
