It is to his extreme advantage to say they are lazy, he coaches their only real rivals in Russia right now- B/S. Srin Odessa's post gave a more detailed description about the truth as far as we all know it. One thing is clear- neither Zuhlin nor I/K were fully happy with the coaching relationship. That being the case, it is probably better that they did split. Now I/K have to figure out how to get the levels, and whether they can get them with Mozorov. However, even if they can't, the solution for them isn't to go back to Zuhlin (if he'd have them, which actually, for reasons to speculative to post here in good faith, I bet he would). The solution is to find someone who can help them get the levels and (IF necessary, which it may or may not be, because even if they were lazy with Zuhlin, there's no reason to assume they are now) put in more time on the ice.
Staviski works with zhulin so maybe you can ignore him but why would tarasova also say I/k hate training? She is a cheerleader for every skater but I/k! Lol. Is it that the whole Russian skating establishment against I/k because they support b/s? But why b/s over I/k when 2012 worlds and 2013 euros I/k were better or almost exactly even? Is it it because they know they can't trust I/k because they hate working hard and training? Level 2 means something and says something.
