I'd like to believe that...but
I feel like Luke is one bad helmet hit away from being done for good. That is not a great position to be in with your best defensive player who likes to get stuck in on tackles.
I'm still not convinced our corners can cover anyone consistently. I read Stewart's thoughts on McCaffrey and thought "well yeah, of course it looks like nobody can cover him when our guys are trying to cover him"
It'll take a couple games before I believe all this speed at WR translates to production. We're relying on a lot of youth, a guy in Funchess who has never had that big season, and a fair amount more from Benjamin than we've gotten. McCaffrey can only make up for so much, and he's a rookie.
(in the interest of full disclosure I was just in San Fran for work and going back there always reminds me of being at SB 50 for that hot mess)
