Rookie quarterbacks Fernando Mendoza, Ty Simpson, and Drew Allar emerged as top performers during the first week of the NFL preseason [1].

These early performances provide critical data for coaching staffs as they evaluate new talent and determine depth charts before the regular season begins.

Different analysts have highlighted various standout players based on their specific metrics. Some rankings place Fernando Mendoza as the top rookie performance of the week [4], while other reports identify Drew Allar as the surprise leader in passer rating [4].

Allar showed significant efficiency in his early action. He led three drives and totaled three touchdowns during the opening week of the preseason [1].

Jalon Daniels also recorded a productive debut. He completed 10 of 15 passes for 111 yards and one rushing touchdown, finishing with an 88.5 passer rating [1].

Ty Simpson joined Mendoza and Allar as one of the most impactful rookies in the first round of games [1]. The performances across various stadiums have given teams a first look at how these players handle professional speed and complex playbooks.

While preseason statistics often vary wildly from regular-season production, the ability of these rookies to lead scoring drives suggests a high ceiling for the incoming class [1, 2].

Drew Allar led three drives and totaled three touchdowns in Week 1 of the preseason.

The divergence in rankings between passer rating and overall performance highlights the tension between efficiency and impact in rookie evaluations. While a high passer rating indicates precision, the ability to drive a team to multiple touchdowns—as seen with Allar—often carries more weight with NFL scouts during the preseason evaluation process.
