That same premise is why I might be alone on an island...but I firmly believe the Browns got the better end of the deal.
A running back is NEVER (yes Adrian Peterson is a exceptin but he's a once in a 10 year back) worth a first round pick. The Browns managed to get a first round pick with a running back who already has a full year of service given as well.
A RB's shelf life in the NFL is basically 20 minutes. I found it pretty funny that Ditka was heavily defending the Richardson trade, from the Colts perspective, this morning. That's the same dude that traded his entire draft for Ricky Williams.
If a running back is truly special, he's worth a top 10 pick. There is no other position where being picked in the Top 10 correlates more closely with a HOF career: Marcus Allen, Jim Brown, Earl Campbell, Larry Csonka, Eric ****erson, Tony Dorsett, Marshall Faulk, Walter Payton, John Riggins, Barry Sanders, Gale Sayers, OJ Simpson, LaDanian Tomlinson and Adrian Peterson were all Top 10 picks. Emmitt Smith and Franco Harris were also first rounders.
But here's why Cleveland was smart: Trent Richardson is not a special back. He's a good back, but he absorbs too much contact. Lamar Miller is every bit as talented and he was a fourth rounder.
