I don't really make predictions. But I Can't very well disagree with the OP at this point. It's a good possibility. All three have it right there for them. Now they have to finish. And it's not can NA finish. NA isn't competing. It's can IMT finish. Can TSM finish. Can c9 finish. That is who is competing. What NA as a region has done in the past is irrelevant. It's all what they do in the here and now.
I'm going over each one individually in the order they play.
IMT. They admittedly had some jitters. I was most concerned about that. And yet they're still 2-1. They got LZ out of the gate which imo was the best match up for them. Get in and get your feet wet with a team you don't have to beat and aren't remotely expected to beat. Then you get the games you have to win later. That said they still have a rookie at the most important position. Not just a worlds rookie. Flat out a rookie. So far so good.
We might know late in the evening/Around 2 am the next morning after depending on Time Zone with Imt. I'm certainly hoping we do. Long story short if IMT and LZ both win their first games, then they both will be the ones getting out of that group in some order. I certainly hope it happens. If LZ loses, then we might know after game 3 if IMt wins that one. IMt is in good position. Beat GAM and you're almost there. Then if LZ does the work for you, it's done. If not, then IMT could finish the job in Game 3. Gam is a dangerous team. I love their cheese. But they're not a great team. And given that Fnatic is airing their dirty laundry in public, they look to be in complete disarray. They didn't play together as a team. Their behavior shows they aren't together as a team. Just bad signs all around if you're a Fnatic fan. Who knows, any given day, anything can happen. They may come together, be the first 0-3 team ever to eventually get out. But it's looking bad right now. I like IMt's chances. But even if they don't get out, I'm still happy. That they're even here is a great result considering. Everything from here is gravy. It looks like we've found an ADC for the future. We've found our leader we desperately needed and got rid of the toxicity and immaturity we didn't all in one trade. Remember when everyone said CLG got the best of that trade? Oh and the coaching has improved tremendously.
The next night no NA teams are involved but we could know with that group after Game 3.
The next night is the TSM group and we could know something by game 4. If TSM beats both WE in game 2 and MSF in game 4 then TSM is guaranteed to get out of group. Those are the must win games. And unfortunately, We and MSF play last so the result of that one won't be known. And if things come down to that match uh well cardiac arrest time for TSM fans. If they then beat FW too, they are guaranteed Top team out of group. We might know earlier if the FW can upset someone. Hopefully they'll upset every team not named TSM. If TSM loses one of those first two, it's probably going down to the wire. Could be a long night for TSM fans. Their position looks the most precarious at this point. Misfits is better than most thought and We is equal competition to TSM. FW by going 0-3 didn't help anyone out. Still to be 2-1 at this point is fine. I'd rather have things in my hands and be in position than being out of position. It beats being 0-3 that is for sure.
Last but not least C9. SKT is looking a bit vulnerable but hopefully they'll knock off the other two teams vying for 2nd and drop one to C-9. They play IHQ in the first game. Go SKT!!! Cloud 9 plays EDward in Game 2. Of all the 0-3 teams, I think Edward the most likely to bite someone. Hopefully it isn't C-9. But even if C9 loses, they're not out of it. Having ED two games behind you going into the final day is nice. Hopefully the first three games will go SKT>AhQ, C9>ED and ED>Ahq and then we'll know. Otherwise things could go late.
