A definite paranoia paradigm pick. The Colts probably didn't hide their interest well enough and someone else in their division mentioned off-handedly (while trying not to break out in a shit-eating grin) that they were going to draft Clarke if he fell near the 2nd round.
This is difficult for us to fathom sometimes but a team can get so high on a particular player that they convince themselves that everyone else covets that player too, forgetting that the other teams have different wants and needs. In the first round, especially, teams should avoid reaching. So what if a player slips by you? You can probably trade a couple of lesser picks to get him from the drafting team if you really want him, and meanwhile you've gotten more real value for your first round money by drafting a player projected as a 1st rounder.
Keep this in mind when drafting for a fantasy team. Sure, you want a guy like Shockey or Gonzo for your TE but in many scoring formats they're not going to give you the production of a top RB, so drafting one of them in the 1st round isn't a value pick. It's good to do some upside down mock drafting to see what happens when you focus on Defense, TE, and Kicker in the early rounds. You generally see why most winners draft those positions so late. In a live draft, I'd rate the top few TE's ahead of even the best WRs (because the separation is so great between a top TE and the "average" TE). In an automated, draft by position league, I'm going to draft TE pretty late because 5 other guys trying for TEs ahead of me in the 3rd round would leave me with a TE who wasn't much better than the TEs I could get in the 8th round or later. I still cringe when I think of a 12-team autodraft I did last year where 10 people drafted QBs in the First Round. Because of the weirdness, I ended up with 3 RBs who all should have been 1st round picks. And you know who all those guys were trying to get? Kurt Warner. ROFLMAO
