But this doesn't appear to be about gathering any type of game-specific intelligence, as the Patriots didn't make contact with McCarron until Wednesday, flew him to town for a workout late Thursday afternoon and didn't sign him until Friday morning.
Now while the Pats have some injury issues at the wide receiver position, you know darn well that head coach Bill Belichick is trying to gain any advantage he can over the Texans heading into this Sunday's showdown. "He's smart and tough, he's played through injury already with a sore thumb".
In their continued quest to get more help at wide receiver in the wake of injuries at the position, the New England Patriots have reportedly added a practice squad slot receiver who's received some positive reviews.
A former walk-on at Iowa, the 5-foot-9, 185-pound McCarron went undrafted out of Iowa, and worked his way onto an National Football League roster this summer as a longshot. If he follows in Welker's footsteps, he could see work as a kick returner and catching passes in the slot.
Does he replace WR Julian Edelman, who is out for the year? Certainly not, at least not right away. However, Edelman did take over for a lot of what Welker was doing when Welker went to the Denver Broncos. The new No. 84 was later identified as McCarron.
