"He looks better," running back LeSean McCoy told The Buffalo News, according to NFL.com's Kevin Patra. "I think he looks more confident. I think last year he just played off of talent. Sometimes, when quarterbacks are really talented, you overlook how smart they really are. Josh is smart."
Though he excelled scrambling outside the pocket, Allen took time to find his rhythm as a passer in Year 1. The young signal-caller completed 52.8 percent of his passes for 2,074 yards, 10 touchdowns, and 12 interceptions across 11 starts.
Despite Allen's up-and-down rookie year, McCoy believes his expected progression as a passer in his sophomore season can significantly boost last season's 30th-ranked offense.
"Your second and third years pretty much are always (better than the first)," McCoy said. "Maybe not with numbers, but just like with confidence, knowing what to expect, knowing what to look forward to, those type of things. So, I'm all excited to see how he plays this year."
The Bills' front office acquired a number of offensive players this offseason to help Allen in 2019. Frank Gore and T.J. Yeldon were free-agent signees at running back, while veterans John Brown, Cole Beasley, and Tyler Kroft were added as pass-catching options.
