Receivers picked between pick #17 (what would have been Carolina's 1st round pick had they not traded up for Everette Brown in 2009) and pick #48 (where Carolina picked Jimmy Clausen).
#22 - Demaryius Thomas (94 receptions, 1424 yards, 10 TDs last year)
#24 - Dez Bryant (82 receptions, 1382 yards, 12 TDs last year)
#42 - Rob Gronkowski (55 receptions, 790 yards, 11 TDs last year, in 11 games)
omitted #39 Arrelious Benn for irrelevance. And I know Gronkowski is a TE, but I felt the need to throw him in there.
Both Thomas and Bryant's stats were better than Steve Smith's last year (73 receptions, 1174 yards, 4 TDs) so you're already wrong. Carolina has had a chance to draft receivers better than Steve Smith. Poor draft decision making has prevented that from happening.
Receivers picked between #33 (what would have been Carolina's 2nd round pick had they not traded up for Armanti Edwards) and #65, where Carolina selected Terrell McClain.
#58 - Torrey Smith (49 receptions, 855 yards, 8 TDs last year)
#59 - Greg Little (53 receptions, 647 yards, 4 TDs)
#64 - Randall Cobb (80 receptions, 954 yards, 8 TDs)
omitted #44 Titus Young for irrelevance.
If Steve Smith went down Carolina would easily have the worst WR corps in the league. Don't say they haven't had the chance to do better, because they have. Hindsight is 20/20 but when your top receiver is 34 and for over a decade they haven't been able to groom someone behind him, something is seriously wrong. Maybe Gettleman can find someone.
