I just wanted to add some comments from Len Pasquerelli's debut article at National Football Post website about the 49ers & the notion of moving VD to WR:
*There’s no doubt that San Francisco coaches are concerned about the absence of wide receiver Michael Crabtree (Achilles) from the passing game. But the suggestion that the Niners are considering moving Vernon Davis full-time to wide receiver, based on his extensive “reps” at the position in recent sessions, are overblown, the 49ers tell NFP. There are some new wrinkles planned for Davis, who can stretch the field like few tight ends and who possesses unique abilities, but he won’t morph into a full-time wideout........
There is a bit more to this paragraph, so if you want to read it, feel free to click on the link and give 'em an extra eyeball.
