As far as Lockette, he's a physical specimen, but I'm not buying the hype at this point. He hasn't put it all together and frankly I think he will not be this breakout player like some expect. I think he may make some plays here and there, but I'm not expecting anything more than "modest" totals at best.
The only thing Crabtree wasn't considered was "Fastest receiver on the team." Everything else -- hands, strength (Boldin of course would contest that now), route-running, open-field moves and breaking tackles, he all was the top guy for those.
It'll be very interesting, but I hope Patton and Jenkins can contribute in amazing ways until Crabtree returns.
