He's the same size (one inch one way, a few pounds the other, but essentially the same size) as Hunter, but he's faster, quicker, and has better open-field vision. Those are the things you can't teach. Hunter's a more refined player now, but the difference in athleticism is where Patterson pulls ahead.
Also, you keep throwing out Hunter's stats, but without context. Three of his receiving touchdowns came against Troy. Three more came against Georgia State. One came against Akron. That leaves two (9 touchdowns, not ten like you've been saying).
From what I've seen it's a 4.43 to a 4.48 and again Hunter was coming off a ACL injury and wasn't at full speed most of the year.
Then I can throw out stats because they were on the "same team". It's not like they played different competition unless you include the "fact" that teams put their best CB on Hunter. Also you can see from the film that teams would often shade coverage and double team Hunter. So yes stats can be used in this debate.
