Many of the draft gurus, Kiper et.al., were critical of the Pats picking him in the first round.
I'm no expert but I have made WR evaluation a hobby for the last 8 years and I've learned a lot about it. Plus I slept at a Holiday Inn a couple of times during that span.
I had him slotted as a 3rd to 4th rnd pick primarily because of his slow 40 time, disappointing agility times, short arms for his height and poor route running skills. It was disappointing to me that the Patriots chose Harry at all but IN THE FIRST ROUND?! The Harry pick was so far out of bounds for what BB has traditionally liked at the WR position - it made no sense whatsoever. Something was amiss.
We got a hint the very next day when we saw Caserio on TV frothing about Harry's contested catch ability followed by "receivers don't get open in the NFL any more. Contested catch ability is more important in today's NFL". Bullshit. A couple of days later I had my answer. Caserio had been beating a drum for Harry to be the pick for a couple of weeks and in the end, BB gave in to Caserio's constant nagging.
Picking traits over production is fine for later round gems or small school prospects. The benchmark for receivers to be a high pick is to have at least 30% of his team's production for receptions, TDs and yards. And speed is all important for an X receiver. A 4.4 40 is the absolute cutoff point for an ideal WR1 at X. Harry ran a 4.53. People wonder why DK Metcalf was an instant success but it's really not a secret. He ran a 4.33 40, had a 41" high jump and an 11' broad jump at 6'3" tall weighing 228 lbs. He has 35" arms and 10" hands. Wonder no more. He's the ideal X receiver from a physical and athletic pov. Seattle got him at pick 64. You can't teach speed, athleticism or size and Metcalf has them all. Harry only has the size.
I'm certain Caserio learned a lesson there albeit at great cost to BB's reputation. There's a lot more to evaluating a proper WR than production, agility and speed but those 3 are table stakes that either get a guy into the conversation or eliminate him altogether as a high round pick. Harry didn't measure up and should never have been in that conversation.
