Their lack of stats wasn't surprising, given how Kevin Rogers kept insisting on running the vanilla option that was so easy to predict.
Javin Hunter and David Givens are two examples of wasted talent. Those guys were both blue chip WR recruits and highly coveted by many schools.
Javin Hunter ended up starting 4 games as a rookie once he got to the NFL. Unfortunately, a ripped Achilles tendon all but crippled him.
When David Givens got to the NFL, he became an excellent receiver, and even had a chance to be a true WR1 when he signed that massive contract with the Houston Texans. Unfortunately, he got his knee shredded up, and never recovered from it.
I doubt that BJ Johnson would have thrived under the overly simplistic Kevin Rogers offense (complete with those stupid overly exaggerated handoffs). At best, I'm guessing he would have been a glorified, pint-sized blocker on running plays.
