As a personnel guy this would be one of my primary focuses, finding as many weapons to slog the offense through the red zone mud as I can. That goes for OLs, RBs, TEs, even QBs. The way the NFL is evolving, teams that have well coached offenses are finding it easier than ever to move the ball between the 20's and get into scoring range, but it's the teams that can keep moving that ball through the red zone and punch it into the end zone that are differentiating themselves from the rest of the league.
I actually LIKE Tony Sparano's idea up in New York to make Tim Tebow essentially a red zone QB/RB. I would consider signing Plaxico Burress if I thought it would earn me some red zone real estate. I would look at tailbacks that are particularly good in the the tight spaces seen in the tight red area (e.g. Jonas Gray, NOT Daniel Thomas). I would look at quarterbacks that have an unusual efficiency near the goal line (e.g. Ryan Tannehill and David Garrard, NOT Matt Moore).
0 to 10 Yard Line Touchdowns, Attempts, Efficiency
Daniel Thomas 2011: 0 TD, 10 ATT (00.0%)
Lamar Miller 2011: 2 TD, 10 ATT (20.0%)
Reggie Bush 2011: 3 TD, 11 ATT (27.3%)
Matt Moore 2011: 10 TD, 36 ATT (27.8%)*
Ryan Tannehill 2011: 14 TD, 27 ATT (51.9%)
David Garrard 2010: 12 TD, 23 ATT (52.2%)
Jonas Gray 2011: 9 TD, 12 ATT (75.0%)
*Note: Matt Moore had an interception in tight red, while Garrard and Tannehill did not.
