As with each full round of Rugby League, Round 1 saw eight teams' fan bases emerge with smiles on their faces while eight fan bases have to wait at least another week to celebrate a victory in 2023.

That said, some teams will be far "happier", or perhaps less upset, in defeat than others.

While it took a perfectly executed field goal by one of the game's elite halfbacks to sink the Panthers, the Dogs were played off the park by the Sea Eagles.

As with every weekend of rugby league, there were positives, which we will cover in an upcoming piece, but also negatives.

Below is a look at five things from Round 1 that should worry fans.

Of course it is only Round 1. Historically Round 1 results offer very little significance later in the season, but performances can.

Not all points will cover all fans but will focus in one something that should worry, at least in the short-term, a specific group of fans.

2. Luke Brooks

At the completion of this entry, I am going Luke Brooks negative free for an extended period.

Tigers fans entered 2023 on the back of a massive off-season that has given them reason to believe this upcoming season will be very different.

Two superstar recruits, two returning run on players with massive amounts of promise, and a new/returning coach and new vision.

Every second page across every publication was dedicated to how it was the season of Luke Brooks. It was his side now. This was the coming out party we had been promised the past five seasons.

Fast forward to the completion of Round One and Tigers fans are already calling for Brooks to be dropped in favour of Brandon Wakeham. For the record Wakeham absolutely slayed the Roosters in NSW Cup in Round One.

Adam Doueihi was irresistible on Sunday evening. He scored a brilliant solo try, kicked his side out of trouble and forced multiple sets.

Luke Brooks ran for 192 metres but offered very little creatively. He missed six tackles, only making eight.

Doueihi has to be the main man at the Tigers. I don't overly care about what number is on his back but he is the seven moving forward.
