we have so much cap space that a 2 year deal would not hurt us really at all, even if he busted like Agholor did, the damage would be minimal but Hopkins is multiple tiers above Agholor in terms of talent
an elite veteran on the outside would really help out all the other WRs, including the young ones, and help Mac tremendously as well. Parker hasn't been able to deliver that for us, and Hopkins is tiers above him as well
Hopkins has consistently been one of the top WRs in the NFL every year of his career, with exception of his ACL injury recently and suspension.. but even after coming back from 6 game suspension last year, he immediately became Cardinals #1 WR and produced
Boutte and them can be put on IR to continue to develop, very unlikely a late round rookie WR, nevermind 2, would make immediate impact in year 1.
I'd actually be in favor of cutting Slater or another ST specialist to carry +1 more WR on the roster, because the position has been that dire for quite a few years now
