They got him listed at 185. He doesn't look much different from the first day they drafted him. If he weighs 175, it's soaking wet.
Tallon said he needs to get quicker. How much quicker can you get when you weigh 175. You are either quick with fast twitch or you're not. It's the same story with Ek improving his skating. The only guy over the last few years who looks faster is Barkov (like you said, he lost some baby fat). These guy look at Gaudreau and Panarin who have little in the way of strength and forget they both are quick and fast enough to avoid the checks plus play the game at a supreme level.
I'm going out on a limb here and saying Boo is going to be on the hot seat by Thanksgiving. I'm basing this on the fact that Lu looked his age in the two starts and Reimer is a notorious slow starter. The 22+ minutes a night will be back in vogue for our top 2 centers very quickly.
