For my money, I would take Bess all day long and its not even close.In his last 7 games dating back to last year (to the game where he became the starter), he has averaged 6.0 catches per game & 60 yards per game. He has had at least 5 or more catches in 6 of those 7. If he held that pace for a full 16 game season it would yield 96 receptions & nearly 1,000 yards. 96 receptions would have tied him for 4th most last year. I dont know if he will hit that number, but he certainly has a solid chance to pull in 80 receptions.
Sure, but now that he has achieved some playing time DC's and subsequent defenses will begin to gain a focus on him. On the other hand, Crayton is a seasoned veteran and has been around the block a time or few. Crayton is very savvy, believe me. He knows how to run in an open field, which is all the more reason he is a punt returner.
Truth be told, I have both Crayton & Bess on my bench in both of my leagues, so I like them both. Everything that you say is true about Crayton, but.... he's in his 7th season. He hasnt been a world beater to this point and its not often that a WR breaks out this late in his career without ever showing something in his first 6 seasons. Thats not to say that it never happens but I like Bess more because he's in his second year. There is a big difference between a rookie reciever and a second year guy. With a year under his belt, he should be able to be more instinctive. He'll be able to spend less time studying where he is supposed to be on the field and more time studying how to get (keep getting) open.I think Crayton is likely to have more TDs than Bess, about the same yardage and far fewer receptions. Since TDs are hard to predict, I think Bess has a better chance to outperform Crayton in a ppr league than vice versa. Non ppr, I would take Crayton. I should also add that I have been wrong plenty of times before.
