I think the concern with Wilson isn't really where he ranks against Fitz and Boldin. Just making that comparison right now is insane. He's not as good as those guys.
10 Games into Fitz's rookie season he had 73 targets, 38 receptions, 557 yards, and 4 TDs. Michael Wilson has 39 targets, 28 receptions, 435 yards and 2 TDs. Obviously different eras, and one was the 3rd overall pick and one was a 3rd round pick.
I'm more interested and interrogating the facts that Wilson is 15th among rookies in receptions and 7th among rookies in yardage. Makes sense that he's being less productive than Jordan Addison and Zay Flowers for the same reason it makes sense that Boldin and Fitz were more productive.
I expected Wilson to have a start to his career like Puka Nacua's, not to get outpaced by Tank Dell and Josh Downs. Hopefully he gets more reps with Kyler and earns more of a spotlight.
