I also think it might have been Slaunwhite not wanting to sound critical of the bulking up approach. I've seen previous interviews with Slaunwhite where he has indicated that his approach is all about speed and quickness and lean muscle development. At the combine a few years ago he made that clear.
I think the fact that Slaunwhite appears more engaged with Laine this off season and has focused on getting him to lose some weight indicates that he might think Laine overdid the bulking up last year, but tactfully avoiding any direct criticism.
Also, I don't think the Jets were happy when other young players bulked up at the expense of quickness, particularly Ehlers and Morrissey. I think it was viewed as a mistaken approach by the team and players.
It's possible that he meant something other than what he said, but if I take him at what he did say, then the training has been successful both years so far. I think he was just as involved with Laine last year. There is a video on the Jets website right now where he is training the prospects and it almost looks like 100% lifting and strength moves.
I guess we will never know unless he pops by here, but I have to take him by what he says. That's all I can do.
