So far, Crabtree has had 5 receptions for 56 yards against the Texans and 6 receptions for 81 yards against the Colts.
Those aren't superstar numbers and he hasn't had any explosive 70 yard catch and runs, truck-sticking strong safeties (which he will), but that's solid production for a rookie that missed all of training camp.
His average is 68 yards per game and if you translate that to a 16 game season... 1100 yards receiving. Of course, that's a poor estimate with only two games under his belt, but it's a nice thought... coupled with the fact that he's continuing to learn the offense and we're transitioning to be a more passing team, I think his numbers will go up... I think he'll have some nice production this season.
I'm curious though how teams are playing him. Has he run into any double-coverages yet? Some of his catches have been on out and curl routes, while he's had a few over the middle.
