With any skill, you are expected to get better at it with more time and practice.
That is the case for plenty of NFL players as they transition from the college game to the pros, having to adjust to the increased speed of the game and the elevated level of competition that they face on a weekly basis. The rookie season tends to be a “trial by fire” experience for many players who are attempting to jump on the moving train and learn on the fly, expecting to get more comfortable by Year Two in the league.
This appears to the case with Pittsburgh Steelers QB Kenny Pickett who was quite literally thrown into the fire last season, coming off the bench at halftime in Week 4 against the New York Jets in hope of sparking a stagnant offense.
