Not entirely sure why, but I've always found Grewal a fascinating guy. VN's got an essay by Grewal up, which includes the following:
When will it end? When Floyd Landis or Tyler Hamilton or any one of the many other "all prisoners are innocent," fallen stars finally and ultimately does hard time. Don't think they won't, they will. Who are we kidding? Prisons and jails are filled with men whose transgressions are much less. Face it people, come on now! Trading $70,000 for a briefcase of refrigerated hot-rod blood, your own or someone else's! Drive it across international borders, for some bike rider to drink and be celebrated as some kind of cult worship rock star for winning a bike race? Have we lost our bloody minds?
I don't think Grewal can be accused being the most thoughtful fellow around, but I found it worth reading. VN also has a Wilcockson interview with Grewal in the most recent print issue. Will have to put my hands on that, soon.
