I'd give game 1 to the Raptors already, except there is an early rally from Bucks in the 4th quarter:
Pascal Siakam with that buzzer beating 3 to make it a 7 points lead for Raptors going into 4th quarter, Raptors have been pretty solid at defence forcing Bucks to shooting from outside, and they are doing that ineffectively.
I thought that the Raptors will steal Game 1 on the road but they run out of steam in the 4th quarter. Lots of turnovers, missed shots etc. The Fatigue is also a factor for them so the last quarter is the time for the Bucks to regain the lead.

Anyway, good game for both of them. I didn't see Giannis defending Kawhi and vice versa but its a close game. I will not be surprised if this will go to a Game 7
. It will be more exciting to watch 
I like to see that, of the two series, this series has a better chance of going into distance.
Bucks has to win game 2, but I am seeing lots of Raptors fans here also, so whoever team will advance in the NBA finals, I would be happy.
They really had a good chance to win, actually in the first three quarters, they are ahead. They just loss steam in the last 10 minutes or so. Lowry provided the spark for the team, but the rest including Leonard had a bad shooting.
Maybe they are really tired and exhausted after a gruelling series against the Sixers. But I'm sure they will be back next game and try to steal game 2.
The raptors sure had minimized Giannis output but still they lost to the other match-up. Lopez step up his game and also Bledsoe has done well in breaking the raptors defense. Though it's too early to celebrate but I guess it's a Buck's series and they will end it in 5 games.
I don't think they contained Giannis. They know that they have been in this kind of situations before. That's why other players step up, Bledsoe has been consistent, but the big difference is really Brook Lopez. We thought that his best days are with the Nets, but it seems he did contribute big in getting a win in game 1 so kudos to him. Bucks is the favorite to win in this series so yeah probably in 5 or 6 games.
