The problem with all first-year-wonders is can they stay healthy.
RG3, Wentz, Saquon Barkley, LVE, etc. are just a few of the NFC East "going to change everything" players who showed glimpses of something special their first year only to get injured and never live up to the expectations their team's fans had.
Parsons is an amazing player, one of the best defensive push rushers I have seen in a very long time, but here we are in year two and he is already dealing with injuries.
As I said last season, as great as Parsons is I will hold the anointing oil through 3 seasons before labeling him as destined for the HoF.
I greatly admire his ability to perform at a high level through injuries and sickness so far.
While the Cowboys defense is good even without Parsons, there is no question he elevates their defense every play he is on the field.
