Are you serious?
Engram is projected a late 2nd, 3rd round pick. He's 6'3 235 not 6'6 250 and he doesn't have the tools of Howard. Howard has all the tools at a Superior size. It's not just straight speed. Although Engram was faster in the 40, he was slower than Howard in the 3 cones, the 20, and the 60. Howard had the fastest TE times in all those cats. At 6'6 250. Don't underestimate his size.
Again I ask, are you serious?
You're comparing apples and oranges.

Compared to MW and Engram, I rather have MW. I like OJ because he's big and as fast as receivers, lining up against safeties and linebackers which will make him truly elite.
Don't get me wrong, if we go a different route in the 1st round (I rather the Bills trade down and get Sidney Jones, now that he's hurt), I wouldn't mind the Bills getting him in the 3rd.
