As I said earlier in this thread, he reached a top speed of 22.3 MPH, which is tied for the 3rd fastest time in the NFL in the past 6 seasons.
Heights are often inflated in college. But anything over 6' is good enough.
Coleman is projected in some places as the 4th best WR. They will have to take him in the 1st. But they absolutely need a speed WR. Now the place that rated him 4th said he runs a 4.45 (I saw 4.57), which could change things.
