Maybe Pace is not the right word.
It's more to do with Rice being a player who tries to read the opposition attack before it actually happens which is my favourite thing about him. He is repositioning himself all the time and constantly guarding those dangerous areas where the opposition could find themselves in space or just have one last defender to take on.
He is great at that and he actually doesn't make a tackle unless his team mates are back in the correct areas. He wants to hold off the dangerous positions first and making sure his team mates have gotten back to the right places before actually going all out to make the tackle. This means he knows he can make the tackle, maybe even fail but all his defending team mates have set up to guard the goal anyway.
The thing that I've noticed is that whilst it is extremely rare because of his great positioning - if an opposition does get past him and through on goal, the ability for Rice to chase that player down, catch up with him and make a slide tackle is not there as much as his other defensive abilities.
He is more proactive with his defending than a reactive one. If he can add some reactive ability towards his game and learn how to add some vertical passing to his game - he genuinely seems like a player that can really make those clean sheets start popping up for us more often than not.
