KJ Costello was one of the hottest prospects ahead of the 2020 season for good reason.
He showed just how high his ceiling was when he came into Tiger Stadium and broke the single-game SEC passing record with 623 passing yards against the No. 6 Tigers.
That was good for the 11th most in FBS history and the most-ever in a debut.
Costello was money that game, completing 36-of-60 pass attempts (the most pass attempts in history by a Bulldogs quarterback) with five touchdowns and two interceptions.
It wasn’t long after that Costello seemed to fade into the background, though, as analysts observed what some deemed a sharp decline that included a concussion in Oct. 31’s matchup against Alabama.
Costello still shouldn’t be counted out as a legitimate NFL prospect, though.
Here’s a complete breakdown of what a team is getting in the former Stanford signal-caller:
Pros
At 6-foot-5 and 223 pounds, Costello is a larger quarterback prospect. He has strong mechanics and maintains his platform, while rarely ever getting off-balance.
Costello has found success throwing the ball at all levels of the field, and his arm strength is beyond adequate.
The quarterback’s footwork is solid, he has a strong upper-body rotation with a good range of motion. Very poised in the pocket with a powerful presence.
His accuracy and ball placement is generally good, though he has shown inconsistency in both of these areas at times and did have a few blunders at Mississippi State.
