I think Crowder's horrific playoff performance has made people forget just how good he was before his injury (which he will fully recover from). This is a guy we were talking about being our best all-around player, a possible all-star, candidate for most improved player.
I think AB's value jumped a bit due to our complete lack of ability to hit a shot. The Portland/GSW performances really enhanced his all-defensive abilities. Smart also showed he can play big when the moment is big.
If you are a Crowder fan, you should feel comfortable in his future as a C. The other two have raised their value to the point where other teams might actually prefer them. That wasn't the case a month or so ago.
