JV actually talked about this subject before in a podcast with Mike Creed way back, maybe 2013.
Creed was very unhappy at being cut from Slipstream as they were in 2007/08. He wasn't performing and was dropped but felt badly treated. He made some derogatory comment's about the team afterward as well.
Its been a while since I listened to it but Creed asked him directly about it. Basically they discussed how guys who were racing clean felt ****ed when they were dropped even when not performing. They seemed to develop a sense of entitlement. Understandable when many of them were replaced by the likes of VdZ, Dave Z, Ryder etc which made it harder to take for many of them as they knew the score on those guys.
JVs response was more or less, yes he wanted you to race clean but bottom line was he was still running a team, not a charity. He admitted that he could be a ****er but that was part of his job(though he does seem to be very bad at it). Creed was somewhat more understanding having moved into team management himself. There were guys like Frischkorn, Pate, Peterson, Stetina, Howes, Duggan who all kept their places or eventually moved on to other WT teams so it was possible.
Some guys have clearly been treated very poorly, Lucas Eusar was dropped after missing a large part of his final season with a broken leg I think.
I see how people think it encourages doping but I still think it's a catch-22 situation. Tell a guy in Aug/Sep he is going to be cut and he doesn't have many results, then guess what? he is going to need results to get a contract elsewhere. How can he quickly get the form to get results? Doping. How many times have we seen guys pull out an amazing late season run of results? What if the guy gets busted whilst still at Garmin having performed cleanly there until he realised he was being cut.
Can work both ways. The only other alternative is for teams to try and find places for their guys on other teams but how many teams do that? How many of the guys cut(as oppsed to left) from Garmin have gone on to produce better results elsewhere
I think there was a lot more going on between Nuyens and JV than what appeared on twitter. Van Hoff and Dekker were not happy either but he didn't slander them like with Nuyens.
