People also have to look at the 2016 TSM like this.
TSM and other NA teams but mostly TSM didn't stream and was on a tight schedule to constantly improve.
The steaming factor hurt TSM as a team because that's most of the team's revenue as well as for the players.
The tight schedule was something that the TSM members sacrificed to possibly win or in their own words " at least come in 4th"( the sem-finals) was their goal. All that work and ending at 3-3 groups eliminated, I just don't see TSM or any NA team really putting in that same amount of effort knowing it's going on 7 years and NA still hasn't looked good at Worlds as well as it was demoralizing at the end of the day.
D-Lift is a great player and arguably in my opinion in the top 20 greatest League players of all time but he's a feast or famine type of player. He's always been "selfish" or team focused around him but it hasn't really produced to the level that his teammates would give him.
2015 Summer D-Lift was great but looking at the NA competition there wasn't any
TSM - Was a 45 min team that did nothing all game and was the most passive team more so than Jin Air Green Wings if you can believe that!
C9 - Was still recovering from the 2015 Spring Split and loss of Hai for the first half of the seaosn.
So the D-Lift first NA Championship was meh.
2016 Summer D-Lift was really good as well as TSM and sorry Bjergsen but D-Lift should have won the MVP in my opinion. The problem with TSM 2016 Summer was they were so good that they barely ever lost, the problem is most times whenever a team just wins, wins, wins they tend to forget what to do if behind, or if the game gets to the late game(45+) mins.
TSM was awful when it came to the late game back in 2016 and if they weren't ahead in games around the 20 min mark they tend to look confused and most times lose.
2017 Worlds NA
Honestly, I have no clue the format for the 2017 Worlds but I do know NA has 1 team in a playoff best of 1 in which if they lose that 1 game they will be eliminated 1 out of 3 NA teams one and done.
NA seems to always start off hot at Worlds in which maybe the success gets to their heads who knows but always gets destroyed in the second half.
2014
TSM started off 2-1 but ended at 4-2. LMQ started off 2-0 but lost 4 straight games. Cloud 9 started off 2-0 got beat some 2-2 and eventually lost a tie-breaker game ending their group stage at 4-3 but moving on to QT's.
2015
Same story CLG 2-0 - 2-4. TSM 1-1 but ending at 1-5. C9 started off 3-0 but lost another tie-breaker ending their Worlds at 3-4.
2016
CLG, TSM, and C9 2-1 all ending at 3-3 in groups, C9 advanced solely and well it wasn't pretty.
Point is NA had their best chance at Winning or coming close to win in 2016 and I personally am not holding my breath.
NA is behind the 8 ball because of the new MSI/Worlds and it's due to NA's lack of production over the years at MSI and Worlds so it's now much harder on NA.
NA has had so many great leads in Groups and would still find ways to fail or mess it up when the playing field was even but now that the road for NA is much harder what's going to be the outcome ?
( I might be wrong need to check but let's say TSM did advance from Groups and beat out RNG and SSG was still the #1 Group D team, TSM would play on the top side of the bracket with potentially facing either Sk Telecom T1 or the Rox TIgers and TSM would NOT have made it past them sorry but in a Best OF- series and not a cheese BO1 NA would have gotten beat 3-0.
