J.J. McCarthy’s second season under center continues to be a steady evaluation of his NFL progress. His touch and strong arm have produced encouraging moments. His inconsistencies have brought attention to the areas that still need sharper detail.
A recent national evaluation helped explain why certain plays appear unstable and where refinement can be effective.
J.J. McCarthy’s Mechanics and the Challenges They Create
On the “Ross Tucker Football Podcast,” legendary NFL analyst Greg Cosell offered a detailed breakdown of McCarthy’s development. He began by noting McCarthy’s limited NFL snaps. Missed time and shifting game plans have prevented him from settling into a long stretch of live reps.
Cosell said this shows up in sequences where McCarthy rushes through reads or loses control of his base when pressure closes in. To him, that reflects a quarterback still learning how to match his processing speed with the league’s pace.
“At this point in his development, and it does not surprise me at all, that McCarthy has a tendency to play a little fast mentally. And you can see that reflected at times beacause there is a little bit of lack of poise and composure in the pocket. You can see everything is happening a little too fast for him right now,” Cosell said about McCarthy’s current situation.
Cosell then turned to mechanics. He identified McCarthy as a locked front leg thrower. When McCarthy strides, the lead leg often straightens, which stops the lower body from rotating through the throw.
Cosell described it as meeting resistance rather than driving through it. Once the leg stiffens, the motion becomes upper-body dominant. That can lead to inconsistent ball placement or limited drive on deeper routes.
Movement brings out more of McCarthy’s natural ability. A slide inside the pocket or a small step toward the space softens his base and allows the lower body to assist the throw. When he cannot move, the locked-leg habit appears more frequently.
An inconsistent season puts McCarthy 35th in PFSN’s QBi. Cosell stressed that this trait can be corrected with focused mechanical work.
An Unexpected Quarterback Comparison
The quarterback Cosell referenced was Alex Smith, a 16-year veteran who played for the 49ers, Chiefs, and the Washington Football Team. He entered the league as the No. 1 overall pick in 2005 and made the Pro Bowl during his time in Kansas City.

Cosell used Smith to illustrate how a locked-front-leg motion can still function within a successful career. Smith won with timing and accuracy rather than overpowering force. His lower-body pattern influenced certain throws but never prevented him from stabilizing offenses or earning the trust of multiple coaching staffs.
Cosell explained that the comparison is not meant to confine McCarthy to a specific path. It highlights what McCarthy can refine and how his game may grow as he gains confidence and control in the pocket.
Cosell closed by emphasizing that McCarthy’s areas for improvement are fixable. His timing can settle. His mechanics can tighten. His command of the offense can strengthen as the game slows for him. The evaluation clarified where McCarthy stands today and how workable his foundation remains.
