Broncos trade Alphonso Smith to Lions
Smith was at the bottom of Denver's depth chart in the secondary, having failed to live up to the promise he showed as a standout at Wake Forest.
The Broncos traded up in the second round of the 2009 draft to select Smith, dealing their 2010 first round pick (which became the 14th overall selection) to the Seattle Seahawks in the process.
Gronkowski was picked in the seventh round of the 2009 draft by the Lions. Gronkowski played in just two games last year, making one reception for four yards.
