Of course, potentially. I suppose for me he’s just not been a failure from the outset: Solbakken didn’t take off, nor Zenga and the less said about Saunders the better. But whether it was luck or whatever, Lage got a tune out of these players for a period of time and got them to 6th/7th prior to the monumental drop off.
FWIW I think Zenga and Saunders are one of the same, they're both wankers but I digress!
We were a statistical anomaly last season, up until December we were scoring the few chances we created and had the best performing goalkeeper in the league. We were consistently in the bottom 5 for chance creation and goals scored and the same players that were mentality King's under Nuno in recovering points from losing positions were now 91st out of 92.
It just wasn't sustainable, I dont think there was a huge paradigm shift rather things just righted themselves from late January onwards. The people you cite not giving him a chance were possibly more tuned in to the fine margins we were skirting by on rather than being seduced by the results and knew it would likely bite us later on (I'm not claiming to be one of these I didn't turn until much later on)
I said about yesterday's second half tactics werent viable because it only takes a rick/moment of brilliance to cause disaster and if you look at last season, Southampton hit the bar and then Adama wraps it up with the final kick 10 secs later. Sa won us 2 points against Everton with a save from Gordon at the end etc things dropped for us. The farce of Villa away, though enjoyable was just football at its ridiculous best.
As the season wore on we managed to nearly altogether stop scoring, the defence looked more fragile and Lage increasingly clueless, the nadir being Leeds at home with him being the only bloke inside the stadium or watching at home unable to see what was needed.
There were some moments like West Ham at Home, Yanited away etc but with the fullness of his body of work I'm more inclined to view them like Cup upsets or giantkillings where everything has come together, he's proven himself incapable of delivering that consistently.
