He deserved every accolade, but I think Jerry Rice's record is safe.
Fitz had a great stretch of 100+ reception years between 2015 and 2017 but has traditionally been below that number, and had 69 last year.
So in addition to him needing to likely play 4 more years, the Cards aren't the same team they were in 2015-2017, where Larry was leaned upon as the clear WR1.
He is still talented, still arguably WR1, but the team around him is very different -- lots of young, able receivers, a young QB who runs more of an option-style offense, and spreading the ball around to everyone.
I would never disregard the possibility when it comes to a guy like Fitz. But deck seems stacked against him for breaking this record.
