India is going through its worst phase in test cricket... Last English Series was actually like puching above the weight... That was supposed to be KL Rahul's farewell tour... He cannot be more consistant than that (not even at home). The guy is one spoiled brat... (Neither good in LOIs, nor Tests... He is not a complete player to handle both the formats... In fact today it is difficult for even legends/ultra-talented players to handle multiple formats with the demands of modern T20s & leagues... even Kohli, Rohit, Bumrah everyone found that out) Rahul (or management) should have strictly stuck to one format and made that decision long back...
Sai Sudarshan (or anybody else) doesn't infuse any confidence at No.3 (such a crucial batting position - Dravid, Pujara kind of players you need there). Gill showed promise at No.4 (and now he is out of this series, not sure about his captaincy - but as a batsman he definitely showed confidence to handle the No.4 spot which was handled by guys like Tendulkar, Kohli, Vengsarkar...)
Jaiswal is a good test opener (fortunately not spoiled much in LOIs, but he needs a better coach to stay focused and not Josh-Josh-Josh Gambir)
Pant is no more the X-factor player he used to be before injury... For him to make a comeback, he should strictly be kept away from LOIs and even in IPL he should just be part of team and not handed over responsibilities like captaincy (just needs to enjoy the time & money like how Wriddiman Saha did - just do your part)
After the exit of Ashwin & Jadeja on his last legs, India no more has that lethal spin attack at home (+the batting alround ability they bring). England series was kind of farewell to even Jadeja! He performed well there (albeit only with bat)
Shami, Yadav, Ishant were more effective than Siraj & even Bumrah in home tests, which was always a secret weapon in Indian home tests which not many people are aware, and blindly attribute all the success of India in home tests to doctored spin tracks/spinners & batsmen! (Bumrah cannot bowl long effective spells in home tests, moreover he may not sustain the intensity in a long test series)
India literally doesn't have a No.5 & No.6 batsman... Pant is good for No.7 only (even the legend Gilchrist batted in this position only, and that's why he was so effective). This exercise of making Pant, Jadeja, Sundar bat higher in the order won't do any good to the team on long run... If India has to be proper No.1 in tests, it has to follow the past WI & Aus teams... Pack with 6 solid batsmen at Top 6 (one can be a decent part-time spinner/pacer like Steve Waugh, Carl Hooper, etc) + 1 Solid Wicket Keeper + 4 deadly specialist bowlers (3 pacers + 1 spinner overseas & 2 pacers + 2 spinners at home). This is always the proper success mantra in tests in any era!
Indian Test Cricket is in miserable condition as of now... A proper coach can still bring it back to its glorious days...
