Aiyuk figures to see work on punt and kick returns, given his quickness, explosiveness and vision in the open field. The question is how many looks he'll see as a wideout. At 6-1, 206, he has decent size but only average long speed (4.50 40), though his vertical leap (40 inches) and broad jump (128 inches) were near the top of his class. Aiyuk is excellent after the catch, able to make defenders miss, and he finishes off plays like a running back. His fate will likely depend on his work before the catch, however - getting off the line of scrimmage and running strong routes. Luckily, he landed in an almost ideal setting - the Niners let Emmanuel Sanders go this offseason, leaving only Deebo Samuel ahead of Aiyuk on the receiver depth chart. Kendrick Bourne is still around in the slot, but Aiyuk could enter his rookie season as the team's top outside receiver if Samuel doesn't recover from June foot surgery in time for Week 1.
