The 21-year-old suggested that there has been little between the two sides when they have played Rangers, but another factor will see them across the line.
The two sides have met three times this season, and while Grant insisted that there was very little to choose between the teams when they have met - with Mark Warburton's men winning two games to Falkirk's one - he conceded that he expects the Light Blues to clinch the league crown due to their huge following.
"There's no question they're the best team in the league. But whenever we've faced them there's been no gulf between us," he told The Scottish Sun.
"The budget and quality of players is obviously massive but the thing they've got on their side is 46,000 fans every week at their home games.
"That's what will get them over the line and I think they'll go all the way and win it because when you've got that backing behind you on a Saturday they've got no excuses."
It is hardly surprising that the 21-year-old believes that Rangers' support will be the factor that drives them on to the title. Ibrox is more than double the size of the next largest stadium in the division, and almost five times larger than the third biggest ground, so will unquestionably provide an atmosphere that cannot be replicated anywhere else.
And the fans appear to be doing a fantastic job of using that advantage to take the team across the line. Currently, the Gers are eight points clear of second-place Hibernian, while Grant's Falkirk side are 13 points adrift of the top of the table.
And it seems more than likely in Grant's mind that if they continue to fill Ibrox from now until the end of the season, their return to the Premiership as champions will soon be confirmed.
