When you say "stretch the field", I assume you mean "vertically," IOW, work the deep patterns. Even considering that the deep ball hasn't been Brady's strong suit the past couple years, I'd agree that we need more than one guy who can do that. Tate, although he's primarily a KR, seems reliable enough for one of those positions - 18.3 YPC on a 48% catch rate is comparable to most veteran deep guys. Price is really an unknown to everyone but the coaches.
But what we also need (IMHO) is someone who can stretch the field horizontally. We appear to have a surplus of guys who are excellent at working the short/intermediate zones between the numbers, but only one who's been fairly reliable working the short/intermediate sideline - Branch - and he's not young and also perhaps a bit fragile. Price COULD be the guy who steps into Branch's cleats (again, only the coaches would know) and Hernandez COULD expand his route repertoire.
If both those things seem likely to happen (in the view of the coaches), maybe we're not looking for WR at all (FA vet or draftee), although, typically, I think we'd see some form of camp competition from a late-round pick or a 2nd-tier (possibly older) FA vet, even in that case.
If, OTOH, neither Price nor Hernandez in the coaches' view) seems likely to step up as a sideline guy, maybe we're looking for a sideline/deep threat combo (e.g., Hankerson) or just a solid sideline possession guy later (e.g., Austin Pettis).
