Think it's mainly about player development as the U-20 league format isn't getting the job done. If the colt teams start off in a division with the top LL and HL clubs (probably mainly the former) as appears to be the plan there's no guarantee they will ever actually get into League One and League Two. Most of these players don't wind up making it and the colt teams didn't exactly set the heather on fire in last season's Challenge Cup when weakened lineups were often being fielded against them. It's arguably more likely to ease the path of the likes of Spartans, Cove Rangers and East Kilbride into League Two and lessens the danger of smaller SPFL clubs tumbling into a regional league format, if there are now ten plus more teams playing at a national level.
