Sam JonesWhat a week in MLS.The Philadelphia Union rallied back from a 2-0 deficit, Petar Musa scored for FC Dallas, and Nashville SC dominated at home. It was truly a week unlike any other. As always: The Power Rankings are voted on by, give or take, 15 people associated with MLSsoccer.com. The author does not decide the rankings, but he does get a little rush out of moving your team in particular down a few spots when he can.WATCH: Every goal from Matchday 20!1. Nashville SC · 1▲It’s far too early to call the Supporters’ Shield race……HOWEVER!Nashville are the clear favorite after steamrolling Inter Miami on Saturday night. They put four past the Herons, largely thanks to a Hany Mukhtar brace and Elias Saad’s two assists. Nashville are now five points ahead of Inter Miami with 15 games left.Through 19 games, they’ve only allowed 15 goals. Major League Soccer’s best defense and one of the league’s best collections of match-winners have their floor set higher than anyone else. It’s hard to see them dropping too many points the rest of the way.WATCH: Nashville SC outshine Inter Miami in Supporters’ Shield clashPrevious: 4-1 win vs. MIA | Next: 8/19 at RBNY2. Vancouver Whitecaps FC · 1▲The Whitecaps allowed four shots against Seattle, and none were on target. They were in total control during a 2-0 win. It’s their first victory since the FIFA World Cup break and first since Sebastian Berhalter was transferred to Middlesbrough.Previous: 2-0 win at SEA | Next: 8/19 vs. HOU3. Inter Miami CF · 2▼Bad week for the defending champions.Inter Miami exited Leagues Cup in Phase One for the first time, and then Nashville handed them a beatdown in the regular season. In a matchup between the first- and second-place teams in the Supporters’ Shield standings, the Herons were well off the pace in a 4-1 defeat.They’re not out of the race, but a five-point gap feels like a wide one against this Nashville side.Previous: 4-1 loss at NSH | Next: 8/19 at PHI4. Chicago Fire FC · 1▲Early goals from Robin Lod and Djé D’Avilla sealed a mostly straightforward 2-1 win over Portland. The Fire lead the middle of the pack in the Eastern Conference by points and, for most folks, by the eye test.Big note here: The win made it five straight in all competitions for Chicago. It had been a while.Previous: 2-1 win vs. POR | Next: 8/19 at ORL5. Houston Dynamo FC · 1▲Uhhhhh so, have you checked the standings lately?The Dynamo are second in the West and on pace for their best-ever regular season (1.84 points per game; 62 overall).Now, we do have to be a bit of a bummer and point out that three of their last four wins have come against the three teams at the bottom of the West standings.The Dynamo are about to get a chance to prove themselves, though. Their next three matches are at Vancouver, at red-hot St. Louis, and at home against San Jose. Positive results there will go a long way t
