The Cal receiver was clocked by NFL Network's Mike Mayock at 4.71 and 4.75 seconds in the 40-yard dash at his Tuesday pro day, confirming that blazing speed is not a quality Allen offers.
"Let me preface the whole 40-yard conversation with this," Mayock told NFL Network's "Path to the Draft." "Three months ago, I said -- if you watch this kid on tape -- if you like him, he's Anquan Boldin. If you don't like him, he's speed deficient. So I don't really care what he runs in the 40. On tape, to me, he's a 4.55 guy all day long."
