Drafting a wide receiver is a necessary evil.
It's necessary because, as we saw in the Super Bowl and all throughout the playoffs, you need guys that can make plays for your quarterback. When you don't have those guys you're dead in the water. No matter what anyone says you can't get by with marginal talent and "savvy" at the position. You need play makers. On a 3rd & Short the coverage dictates Joe Flacco go one-on-one to the outside with Boldin and he throws up a 50/50 ball that Boldin comes down with. When the Giants win the Super Bowl against the Patriots last year, it's on a Mario Manningham catch that Eli Manning had no business throwing based on the coverage, but he trusted Manningham to make a play for him, and he did. When the Cardinals come back on the Steelers it's Larry Fitzgerald being ridiculous. And when the Steelers somehow come back on the Cardinals at the very end, it's a beautiful Santonio Holmes fingertip-to-toetip play in the end zone.
But it's also evil...because when you look at the straight percentages, it's flat out daunting. So many of the guys we're talking about and getting excited about will amount to NOTHING at the next level. It's just a fact of the draft. So because it's so inherently risky, teams try and take risk off the board any way they can. Being an incredible athlete from a size/speed standpoint takes risk off the board. A guy is usually going to be at least SOMETHING when he's an incredible athlete. But pure speed and agility also takes risk off the board because you know if you teach the guy right he's going to be able to separate.
What I'm getting at is Markus Wheaton with his pure speed and agility, both of which he showed at Oregon State and then he showed against higher caliber competition at the Senior Bowl, makes him a relatively safe guy. Not all guys with his speed and agility have had the chances he's had to show that he's a safe prospect, but one way or another he's gotten those chances and he's taken them...so I think of him as a relatively safe bet. And if he's a relatively safe bet then teams trying to take risk off the board are going to steer toward him, IMO.
