The coach's absence had always been a huge setback for TSM. We began to witness a more consistent winning performance from them after the arrival of Chet in May - Bang and Levi, of course, further boosted TSM's squad. In my opinion, they need a little more time with their current coach and squad to obtain more experience. They have shown that they have the ability to be a top team; they simply require more time to transfer to the next, stable top 3 levels. By crunching the data, an analyst might perhaps improve their roster even more, relieving the coach and their igl of these responsibilities - only about $20k a year. Last but not least, the team's discipline should be top notch, as competition is becoming more fierce, and individual mechanics will no longer be sufficient to win series.
In general, a skilled coach and analyst may boost any new or struggling team in a variety of ways. Their job is vastly undervalued at the moment, perhaps due to Shahzam's excellent work. But not many teams have someone as giffted as Shahzam who could cover for coach/analyst/igl and grow as individual player + stream 6hr every day, if any teams at all LOL. A coach and an analyst can bring order to teams by providing a vision and reassigning responsibilities from players who must keep up with their own personal development. For instance, after losing Johnta, FPX found itself in a very difficult and vulnerable position. Now, their former analyst must serve as both a coach and a data cruncher for the team which is reflected in their recent negative performance. I'm not going to get into this topic in depth because it would require some research, but both SMB and FF hired EU coaches (Tanizhq and Salah) to tackle EMEA, which has proven to work for Turkish talent, especially SMB. FF also put forth a strong effort, but they were unable to advance due to their possibly inexperienced team and the inexperience of their individualy young talents. VGIA also promoted Pipson to full-time coaching, and with the addition of new players, things began to click for them as well.
