As an outsider I really, really like the Hawks receivers. I think Wilson is great (my favorite of the young QBs, TBH), but I think his receivers also bail him out and are turning incompletions into receptions at an above average rate too. I love Tate as a player, think Baldwin is pretty good too, and like what I've seen from Kearse so far (and he's still developing to boot). Add Percy into that mix and it's truly a special group. Sydney Rice was hugely overrated and overpaid, and of the whole group, he was the best one to go, IMO.
It will be interesting to see if the Hawks can keep Tate (as a 9ers fan I'm hoping they can't and I'd LOVE to have him on my team), but Percy will more than make up for that loss if it happens.
So, long story short, I think the Hawks receivers are really good, actually. I think they could use an upgrade at TE much more, TBH. IMO Zach Miller is overrated despite not being rated that high (sorry, really not high on him), and Wilson might develop into a good #2, but isn't the guy. Luckily athletic, receiving TEs have started to grow on trees and can be regularly had in the 3-6th rounds these days. After shoring up the o-line in the 2nd & 3rd I'd probably go to TE before WR.
