They may not be the most glamourous names in Celtic's squad. Their appearances may only engender a shrug of the shoulders from some supporters. They may not have cost the club a eye-watering sum.
But boy have Greg Taylor and Liam Scales made a difference to the champions-elect since their reintroduction to the starting XI.
All of a sudden the left side of Celtic's defence looks a lot more assured and forward thinking.
I say 'defence'. More often than not, centre-back Scales is playing around the halfway line, with fellow central defender Cameron Carter-Vickers for company.
Taylor is often seen in that 'inverted' full-back role somewhere in the midfield. Both are forward thinking, both pretty crisp with their passes and help the team move upfield with purpose.
I remember Brendan Rodgers telling me Irishman Scales was the player who had "surprised" him the most in his managerial career with the way he had made himself a first pick shortly after the manager's second coming.
What surprised me this season was Scales being asked to make way for Auston Trusty. Yes, if you spend £6m on a player, he's not arriving to warm the bench.
Scales, however, has rarely let the side down in the past couple of seasons. He has a cultured left foot when it comes to delivery and distribution, and a committed attitude that leaves you in no doubt he's honoured to wear the shirt.
Yes, he may want a little too much time on the ball on occasion and could do things quicker when the tempo demands. He is, though, fully deserving of his latest run in the side.
Same goes for Taylor, but with bells on. He's possibly the most underrated player in the top flight.
While teams can target his lack of height and occasional lapse in positional sense - that diagonal ball down Celtic's left flank has been a feature of some opponents - his comfort on the ball, and quality of delivery with it, marks him out as a real asset.
Little wonder Rodgers is still trying to coax him into accepting another deal, with Tierney already on his way back to the club.
Taylor is effectively an auxiliary midfielder/winger who's also expected to retreat to left-back when the opposition attack. You need some amount of fitness, energy and ability for that.
After the shocker at McDiarmid Park recently, both Scales and Taylor were restored to the starting line-up. The aggregate score in the two subsequent matches? 10-1 in Celtic's favour, with some of the sparking football from earlier in the season also restored.
Celtic's left flank has markedly improved in the past two games and has had an effect on the rest of the team. The reintroduction of Scales and Taylor is no coincidence.
