Max was very good...even excellent in the lower tiers/formulas. However, Max was darn near phenomenal in F1 almost immediately. Whether such was due to natural evolution or the fact that it is F1's specifics that truly suited him...I do not know. However, I think such debuts in F1 are rare...certainly not seasonal (winning the F2 title does not mean greatness). I hope Tsu is in fact a second, recent lightning strike.
What I fear is that his relative youth/inexperience (yes I am old), F1's disparity in equipment (not as big a factor in F2), and the cut throat mentality in the paddock could dull his edge pretty quickly (heck, Alb appears downright suicidal in recent interviews).
As for Honda...I have been around long enough to see Honda (and BMW) quit time and time again in various motorsports. Personally, I hope RB takes over and succeeds...maybe other small manufacturers will take notice and gain interest.
