I really doubt fans of other teams feel bad for the Pats with their receiver depth. Sure, losing AB hurts, but we have the reigning SB MVP, an immensely talented player in Gordon, one of the best receiving RBs in the whole league in White, plus a reliable receiver in Dorsett, a high draft pick in Harry, and even a solid TE in Watson.
These are 1st world problems, my friends. And this isn't even taking into account the defense.
