Michael Gehlken of the San Diego Union-Tribune had a chance to watch second-year wide receiver Keenan Allen in training camp and came away noticing his increased speed on the field. "He trained at Prolific Athletes in Carlsbad with renown speed coach Ryan Flaherty, their results better speed in and out of Allen's breaks and, yes, an albeit subtle increased capacity to go vertical," Gehlken wrote.
As a rookie, Allen was known for his crisp route-running ability, but his speed wasn't as great, running a 4.71 in the 40-yard dash. Allen now feels faster and said, "I'm a deep threat now."
The report also mentions Allen added some weight to become stronger in the offseason, up about six pounds from 206 to 212. He's poised to build upon one of the best seasons by a rookie WR in recent history and can be considered a WR1 for fantasy purposes. He is currently ranked WR12 in FFToolbox's cheatsheet rankings.
