In defense of SPEED factor, I will say this.
Jerome Mathis was a small school prospect as a WR, and doesn't have a whole lot of polish. He walked into the Combine and tore up one of the fastest electronically timed 40 times ever measured in Indy...the fastest man in the draft. He became a 4th round pick based solely on his SPEED.
And in case ya didn't notice? He just played in the pro bowl this weekend, as the best kick returner in the NFL averaging 28.6 yards per return with 2 touchdowns.
What makes Jeremy Bloom interesting is his skiing experiences, which actually help the man create some tremendous YAC. Not to mention, the guy is just plain an elite ATHLETE. He's competed in and won the annual Superstars competition against the world's elite athletes two years in a row, including NFL stars like (in the latest competition) Ahman Green, Will Allen, Dexter Jackson, LaVar Arrington, and Charlie Garner)...and this before Bloom even turns 22 years old. That competition involves all kinds of things, kayaking, rock climbing, obstacle courses, 100 yard dash (which he ran, btw, in a BLAZING 9.4 seconds...THINK ABOUT THAT FOR A SECOND).
And it ain't like the dude is COMPLETELY new to the football field. He was college football's leading punt returner a few years back. The very first time he stepped onto a college football field, he returned a punt 75 yards for a TD. That year, he also snared a short reception and turned it into a 94 yard touchdown in the conference championship game. Next year, he caught 22 balls.
You cannot, and I repeat, cannot coach speed...and there's no substitute for it. Bloom has agreed that when he's drafted he will sign a no-skiing clause in his contract. He's an elite world athlete with excellent concentration, coordination, focus, and work ethic. And, quite frankly, line him up in the slot and tell him to run vertically 50 yards up the field and he'll get a full 5 yards of separation on the corner within a 5 second time frame (which means the QB releases the ball after a short 3 seconds).
You may think there are a BUNCH of one-trick-ponies in the NFL that have Bloom's speed and running ability, but there actually are not. 9.4 seconds in the 100 yard dash is blazing, absolutely blazing...less than a second a yard. There's a lot of 4.35 speed guys that wouldn't come close to 9.4 seconds.
