Former Wales star Jonathan Davies described the second row as the best player to ever don the red shirt.
Schmidt revealed that some Irish players spent part of the week in isolation after they were hit by a stomach bug, which disrupted their preparations during a six-day turnaround before the match in Cardiff, but conceded that his team had been out-played by a Welsh side that were buoyed by their hunt for a Grand Slam title.
"He (Gatland) is the man at the top and it filters down, we have been under pressure and he has been unwavering and unflappable he has a bit left on his contract but sure we will miss him".
Nothing went right for disjointed Ireland as they relinquished their title with a whimper, Gatland - who will end his long reign after the World Cup - becoming the first coach to mastermind three Grand Slams in the tournament.
The roof of the Millennium Stadium will be open during the crucial Six Nations clash between Wales and Ireland in Cardiff on Saturday.
Gatland, who steps down after the World Cup later this year, still tried to suggest they could creep in to the World Cup unnoticed but fell short.
From there it was all about the boot of Anscombe, the fly-half converting three penalties before the break to send the hosts in 16-0 up at the interval.
"They will run through a brick wall for you and we are a tight knit group".
Ireland received the final say on the roof but Schmidt refused to be drawn on the subject earlier this week, simply insisting his team would cope one way or another.
"We got here with a bit of luck we have a good chance of beating anyone".
"He is a fantastic person and a great player".
Joe Schmidt had explained that Wales defied protocol and asked Six Nations bosses to close the roof for the game. Wales were as low as eighth in the rankings less than two years ago after finishing fifth in the Six Nations.
"We're trying to build those two guys forward".
"If it's closed and wet, we might as well have the roof open and let the rain come in".
