The Buffalo Bills wrapped up their mandatory minicamp on Thursday and will now be off for a few weeks before regrouping in Rochester at St. John Fisher University for training camp. The team held three practices this week and these are some of the key takeaways from this year's minicamp.

Passing game work in progress for Josh Allen and offense

The Buffalo Bills made significant changes to the wide receiver group and the pressure is now on Josh Allen and Joe Brady to get everyone on the same page. It was evident early on in minicamp that it is going to be a work in progress.

The good news is that there were notable improvements as the week went along as Sal Capaccio with WGR550 noted on Wednesday:

"After a sub-par passing day on Tuesday at mandatory minicamp, the Buffalo Bills offense got back on track Wednesday, striking on several deep balls and long plays."

The Bills only have one receiver currently on the roster who has caught a pass from Allen during the regular season, Khalil Shakir (and more on him later), there was absolutely going to be growing pains for this group. The good news is that as the week went along it got better and ended on a high note with this great catch from Keon Coleman on Thursday.
