I think Reagor is a better player but it's hard to tell from last year because TCU had a freshman QB who was a much better runner than passer and so they became a running team. They barely threw for over 2000 yards last year which is why Reagor's stats were down so much.
I'm not knocking Ruggs he is insanely fast, i read he averaged 9 yards after the catch this year, that's pretty ridiculous. But he's basically a guy who does 2 things well, those crossing patterns where he just outruns angles, or the balls upfield where he just outruns people. if you watch him against LSU or teams that have NFL type DB's, he struggles often, he can't get off the LOS clean, he just wasn't all that good against the kind of competition he'll see in the NFL. I would not be opposed to picking him later in the 1st round or if he somehow slipped, the 2nd, but I really am surprised people are projecting him as high as the 3rd receiver, I see him going to the Eagles as a very popular projection.
He caught 98 passes in a year college career, yes they had lots of weapons but I think his catches were low because he's just limited on what he can do right now as a WR. He was a pretty good KOR, not close to what you might think given the speed. Longest return of his career was 40, PR's 2 years in a row that was a thing in the spring they were going to use Ruggs as a return guy to take advantage of his speed, both years they abandoned it because he struggles to track the ball in the air, 8 punt returns in his career, longest was 16 yards.
Reagor had some issues on punt returns too, they put him there this year to get the ball in his hands more because the QB was so raw he was being wasted. He had 2 for TD's, one of them he dropped the punt, fumbled it around then picked it up and went house. I would assume NFL teams will see if he can return at the NFL level, TCU used him a bit on KOR but they didn't want him to get hurt so they limited them, I can see an NFL team using him more. He's more elusive, he is stronger with the ball despite being smaller than Ruggs. he too at times has trouble getting off the LOS and he's not a great route runner but IMO he can do more than Ruggs does in that regard.
Reagors stock is down because of a down junior year and concerns that he showed visible frustration this year and people said lost concentration. Understandable with a freshman QB who was just not very good, Reagor didn't get the ball enough.
Both guys are going to have big explosive plays, I just feel like Reagor is going to make more plays overall, Ruggs is faster but Reagor is going to put up a good 40 and probably a great vertical, he can really get up. He's got more wiggle, he is also incredible at acceleration, but both guys need to learn to run routes, both guys, especially Ruggs, waste lots of steps with their routes, that's actually one of the biggest knocks on both of them but from what I read and what I saw watching Ruggs at Alabama he's a guy who just outran people. Jerry Sullivan would help either one of them with the ability to run routes.
