Jake Bobo is great and the numbers back it up
Jake Bobo doesn't get a ton of targets from Geno Smith, but he makes the most of the ones he does get. He has 13 targets in his rookie year through seven games and he has caught 10 of them for 135 yards. He's also scored two touchdowns receiving and one rushing. Bobo is second on the team in total touchdowns with 3 (in case math is as hard for you as it is for me).
Jake Bobo is third on the team in yards-per-touch at 12.5. His 76.9 catch percentage is third on the team among all players with more than 6 targets. The bottom line of all this is Bobo has been good where the raw numbers apply, but he's also helped the team so much more than just running and catching. Bobo is also an elite blocker.
According to Pro Football Focus (subscription required), Bobo is the 14-highest-graded receiver in the NFL so far this year. He is seventh-best in run blocking, but he is 21st where it matters most: Catching the ball. Time will tell how well Jake Bobo does in the NFL, but he is looking currently like Seattle's latest gem of an undrafted free agent.
Speaking of PFF, they seem to not know what to do when it comes to defensive linemen. Jarran Reed is currently ranked as the 45th-best interior lineman. Reed has been a key reason why Seattle is better against the run this year than last, and he has 4 sacks. Just to be clear, PFF is completely wrong about Reed.
