To compare Andrew Luck and Robert Griffin's futures as professional quarterbacks is to compare apples and oranges. So much depends on the teams that draft them, the coaching staff and the management and ownership of that team.
Sports fans do still have some idea of which teams are likely landing spots for each quarterback: Luck is almost certainly going to be an Indianapolis Colt and he could even be signed by the team a month before the draft starts, while Griffin's future isn't as set in stone. Speculation is that the teams most likely to trade up to snag him are the Cleveland Browns and Washington Redskins.
The Colts, as they stand right now, undoubtedly have more talent at the skill positions than both Cleveland and Washington. Three of their top wide receivers and Pro-Bowl center Jeff Saturday are unrestricted free agents, but even if they managed to sign just two of those four that would still hold true.
If the team must give up at least two first-round picks, a second-round pick and a third-round pick to trade with St. Louis (which is optimistic in itself) to have the opportunity to draft Griffin, that potentially sets the franchise back even more. Now there is less opportunity to build the team around Griffin. The Colts save all future picks, and also have the No. 34 overall pick in the draft, where they can still find a first-round talent (perhaps an offensive tackle to help protect Luck).
There is a reason Luck is regarded as the clear-cut top quarterback in the draft. There is a reason there has been no trade speculation with regard to the Colts' No. 1-pick. There is a reason Luck has been called the best college prospect since John Elway, Jr.: He's that good.
Griffin is a spectacular athlete with an extraordinary football mind. In almost any other year, he would be the top quarterback on every team's draft board. But Luck is just on a completely different level.
Luck redshirted his first year in college and took a back seat to Toby Gerhart in his RS freshman season. In his sophomore year, he threw for 2,575 yards and 13 touchdowns. In his last two seasons, he threw for 6,855 and completed 70.5 percent of his passes.
But the numbers don't do his skills justice. He played in an NFL-style offense under David Shaw and had free-reign over the offense his last two years – similar to the control Peyton Manning had in Indianapolis. Oh yeah, it also doesn't hurt that he put up similar combine numbers to what Cam Newton did last year (4.59 seconds in a 40-yard dash). Luck will have a much smoother transition into an NFL offense than Griffin will, which isn't to say Griffin will have trouble.
There's no doubt that both will turn into great players in the NFL. Luck, however, will have a brighter future because of the situation that will receive him.
