I've rewatched every snap Cleeland has played this season, and after going through the film closely, I came away less impressed than I was initially. This isn't a criticism of him personally; it's strictly an evaluation of his current performance and traits from a football perspective.
After reviewing the most recent game along with the two preceding games, there are several areas that stand out as concerns.
Pocket Movement/Footwork: Cleeland's footwork is inconsistent, particularly when operating from the pocket. He appears overly active and jittery at times, which can disrupt his base and lead to poor weight transfer. As a result, there are throws where he doesn't appear fully balanced or properly set before releasing the ball. Cleaning up his footwork and developing a more consistent base should be a priority.
Processing/Progressions: One of the bigger concerns is his ability to work through progressions. He appears to lock onto his initial read too frequently rather than consistently working through the progression and getting to the next option when the first read isn't available. That tendency is becoming more noticeable on film, and defensive backs appear to be recognizing it. He's giving defenders opportunities to read his eyes and anticipate where the ball is going.
Accuracy/Touch: The arm talent is evident. He has enough arm strength to make throws to all areas of the field, but arm strength hasn't consistently translated into accuracy. His ball placement can be inconsistent, particularly when he's throwing from an unstable base. I also haven't seen a consistent level of touch on throws that require more than simply driving the ball.
Mobility: I haven't seen much evidence of significant rushing ability. While he can move when necessary, he doesn't appear to have the burst or acceleration to consistently turn broken plays into explosive runs. His mobility currently looks more functional than dynamic.
Overall: The physical tools are there, particularly the arm strength, but the overall quarterback operation still needs considerable development. The biggest areas for improvement are footwork, pocket composure, processing speed, progression discipline, and ball placement. Those issues appear to be interconnected, particularly when his base and pocket movement break down.
Based strictly on what I've seen on film this season, I'd currently grade his performance in the C-/D+ range. That's less a reflection of his long-term potential and more an assessment of where his game is right now.
