I wouldn't consider Johnny's comments as trash talking. On the snarky side, yes, but far from trash talking especially considering he's had his share of diva moments. I actually take it as a compliment to Jeremy whose had great success in last year's GP and Nationals. It's a testament to how strong a skater he has become for him to be used as a barometer that he's not out of the loop yet. And Johnny's comments are very true. He needs to have this "out to prove everyone one wrong" attitude because he is more of the classical skater than the one that goes out & takes advantage of the CoP.
Skating well proves he deserves to be on the Olympic Team. Not taking advantage of the current rules in a competition is just not smart. "Snarky" as you term it, is not cool. I just think it's better to let your skating do your talking for you.
I hope he continues to improve his skating and makes the Olympic Team.
