What was the deal with GGG's telegraphed punches early on?

[Chino]

Didn't see GGG do any lateral movements, no bobbing or weaving, just walking straight lines towards Brook. He was taking more than a couple uppercuts as well. Yes he might be able to beat elite competition but after yesterday's fight I realized he is not THAT INVINCIBLE.

Hoping Caneo will take the bait too.

And if that fight ever happens and Canelo gets to beat him I wonder if people will finally give him credit for once or say GGG was too old, too slow, etc.
