I think and from reports that Hendrickson was misevaluated they just didn't think hed be that good. And Baun didn't fit the system, now maybe they should have adjusted the system to fit him though
No one in the NFL really saw Hendrickson rounding into the form he did. A few sites wondered why he was picked that high.
I think the other part of the problem with Baun is that he was playing alongside prime DD and I can see how that could be demoralizing. Now Baun is pretty much the unquestioned guy and he's playing with a lot more confidence.
