I too have no idea what's going on with C9, my theory is
MonteCristo is coaching the team and teaching them about "rotations" and failing like he did with CLG.
C9 Early game -
C9's early game is actually one of the best in the League as far as objectives goes, but they tend to reach too far in doing so. C9 are constantly either in defending dragons, heralds or getting the objectives while the opposing team laners' are still farming up for late game, in which knowing C9 they're not that fast pace team anymore. Last split C9 were around 1st or 2nd longest in game time and had close to 17 or so Overtime games(40+mins games = OT ). Same thing this year C9 are #1 in game length and are overall the second best at dragons around 15 mins 0.75(2nd best), but the lanes are struggling because of it, they all leave lanes together to get these objectives, adding the fact that Jensen, Sneaky and Smoothie are in the top 13 players with the highest kill participation the other teams with multiple players in the top 13 are P1's with 4 players, TL with 2 and TSM with 2 themselves and we all can agree P1-TSM and C9 are all struggling from their last split.
Split pushing
CLG - Darshan, DIG - Ssumday These are top tier teams because the meta is less around 5v5 teamfighting but around split pushing, while teams like TSM/C9 are more " for the team TP players from top etc". Ray may have been freelo to some teams but they dude at least splitpushed while Impact just honestly.... sucks right now. Not even joking but whenever he did that failed Gragas ult at bot tower in whatever game it was he has been going down the drain since, doesn't even look like the same Impact this split.
Overall
Not on the same level as say Ryu and Arrow as far as being beaten in lane but Impact has, Jensen look good as far as stats go but he's not looking that great either and Sneaky/Smoothie are having trouble because the meta is shifting away from this be 300 miles away and just have the support poke for 30 mins, they're needing to actually fight, be aggressive and win lane and asking that from Sneaky who's always been ok in lane phase BUT......BUT really great late-game and a good teamfighting player.
Phoenix One
Pretty much the new Team Liquid I see; Ryu is just losing lane and Arrow is getting focused hardcore style. The other NA teams have figured out that if you just focus Arrow the other mediocre players around Arrow will fold. They aren't like TSM where a team can just camp Bjergsen and win because TSM still has 2 other carries on the team(more of less).
( Is Xpecial even on DIG anymore ? Sorry, missed like half of the streams on Youtube so didn't find out why he was on P1 now?)
Seems like the team needs a shotcaller in my view- Zig isn't going to do it, too young and not enough EXP around his belt yet, Ryu and Arrow are Koreans and just wouldn't make sense to have 2 out of 5 to be the shotcallers with communication being an issue. P1 looked 10X better with Xpecial - didn't win but Xpecial does bring some type of leadership, winning championship pedigree and EXP.
CLG and IMT are playing great and instead of TSM/C9 to represent NA at RR I wish CLG and Immortals would instead, knowing TSM's history and honestly just tired of seeing TSM and C9.
However, CLG are winning but barely at times and very similar to the last split with a bunch of kills and deaths and not really any strategic focus from previous splits but they're winning and a W is a W. Immortals have to be the #1 team in my view and not because I think IMT will beat CLG but IMT are winning games with in theory an inferior roster compared to CLG. I mean people aren't going to mistake Pobelter from Huhi nor from Stixxay/Aphro from Cody/Olleh.
IMT are very similar and identical to how CLG were a few splits ago, less talent across the board but more team focus.
Whichever team wins this next week will win NA 2017 Summer split in my prediction.
