There was actually a lot of criticism of Pastner when things weren't going well--and overall, probably more skepticism of him when he was hired than there was of Collins. Many, including myself, thought it would be reasonable to pursue terminating his contract after the Bell fiasco.
Most Tech fans just want to win, and despite the customary overreaction to individual losses that's par for the course with any fan base, we're willing to be patient if there are clear signs things are headed in a positive direction. However, finishing the second half of the season 0-6 and looking worse every week on defense doesn't exactly inspire confidence. Conversely, while I've had some issues with Pastner's recruiting at times, the on-court evidence is suggestive of a staff that knows what they're doing from a coaching standpoint.
