It's horrible drafting to pick a guy at any spot if you think his upside is as a 4th liner.
Even in the lower rounds you should pick a kid with some ability or quality that if the shortcoming(s) get fixed, can make him a top player. Of course the odds are ridiculously long, but every now and then you get a real good player.
So Flo , didn't produce and he isn't skilled. But he is big even for the NHL, skates decently enough, goes to the net, has a decent wrist shot, is physical and competes. If he has his brothers desire....
Flo has a low, but realistic chance of putting it together and if he does, could become a Tom Wilson type of player. And Wilson is a guy he likes.
No problem with this pick.
