BY BRYAN BURWELL, Post-Dispatch Sports Columnist | Posted: Wednesday, June 13, 2012 11:45 amThere was Steven Jackson on Tuesday afternoon at Rams Park marveling at how quickly time flies. Wasn't it just yesterday when he was an eager rookie looking to take over the pro football world?Jackson now is an NFL graybeard who has seen his football life whiz by in the blink of an eye. After nine years in the league — far too many of them losing seasons — the Rams' Pro Bowl running back has developed an essential gift.An impatient nature.Time is running out on his football career, and Jackson wants to win now. He wants to be a part of a worst-to-first turnaround at Rams Park and leave the game with a Super Bowl ring, and he hopes that this offseason his new bosses did some smart shopping to make the Rams an instant winner.He's in no mood for long-term rebuilding. He's in no mood for slowly breaking in rookies or coddling gifted youngsters such as second-round draft pick Brian Quick. Rather than toss out pleasant compliments to the rookie wide receiver after the first day of minicamp, Jackson issued a rather gruff challenge to his new teammate.Be ready to make an immediate impact."I'm sure (receivers coach Ray) Sherman will get him right," Jackson said. "But over the next six weeks, he's going to have to work real hard to be prepared for a long season, because we're going to lean on him, lean heavily on him. He's a high draft pick and we're going to need someone on the outside to make plays and I'm challenging him right now because we're going to need him to prepare himself over the next six weeks to be a standout on this team."Some rookies get to ease into their NFL life. Some get the benefit of the doubt that they will be slowly nurtured and allowed to grow into greater responsibility. Quick won't be one of those guys. He was the 33rd player taken in the draft and he's being treated essentially like a first-round pick, full of the same first-round expectations. If the Rams are going to have a more productive offense this season, Quick must be a big-play receiver immediately. He will be expected to dominate down field, be a bold, fearless target over the middle and QB Sam Bradford's most dangerous scoring threat.That's why Jackson took the strategic opportunity to challenge Quick publicly. This was no thoughtless improvisation. This was a well-thought-out message delivered loudly and clearly by the team captain. He wants Quick to understand that the six-week interval between the end of minicamp and the start of training camp shouldn't be considered a vacation. Use the time to get better, to absorb the playbook inside out.The time for fun and games is over."He's a big target, but he has a little ways to go," Jackson said. "What I mean by that is he's coming from Appalachian State. Nothing against it, but it's a (big) difference. It's a difference coming on this field and it's a difference having the mentality of a pro."When someone with Jackson's stature calls you out like that, it's not intended to be an insult. It's actually a compliment. It was his way of providing a sense of urgency to the kid who certainly looks the part of a stud wideout the minute you lay eyes on him on the football field. Quick looks even bigger than 6 feet 3 when he walks onto the field and plays even bigger, too. He goes up in the air like a basketball small forward and snatches the football out of the air like a power forward and he can glide down the sidelines like a long-striding sprinter.Like most of the talent evaluators in the Rams' front office, Jackson can see all those wondrous athletic gifts when he sees his new teammate on the practice field. But he also has seen a rookie who had some struggles with the playbook, because he comes from a mid-major college program that ran a spread offense, didn't use a huddle and never had a voluminous NFL playbook."They just sent our plays in from the sidelines," Quick said. "I got the signals, I knew what my routes were and I just ran them. But now it's a lot to retain. It's not real hard, but it is a challenge, and I have to step up to the plate like Steven said."That's exactly what you want to hear from him, too. Quick didn't make excuses. He didn't recoil when he learned that Jackson had issued him such a stern challenge. Instead, he took it all in and responded the right way. He said he's up to the challenge. He said he not only wants to get better, he will get better."I'm in my playbook," he said. "Every day I come out here to get better and I want to be that guy who can help the team. If that's what it takes, if (Jackson) wants to challenge me, I'm going to step up to the plate and make plays and do the things I need to do to help the team and be a better player."The Rams' personnel people are in love with this kid, so much so that they were convinced that he was as good a prospect as the first receiver taken in the draft — Justin Blackmon. Right now, at least from a character standpoint, the Rams have to feel a bit more at ease with losing out on Blackmon because of his drinking issues. Quick had no character red flags and he's bigger than Blackmon and just as fast. But it's way too early in the process to start trying to determine just how good Quick is going to be.But from what we've seen so far in shorts and T-shirts, he certainly looks the part.Right now, I'm right there with Jackson. I hope the kid understands what's expected of him and is one of those rare godsends like another old smaller-school wideout who had similar athletic gifts and a work ethic that turned him into the greatest pass catcher in NFL history. Jerry Rice became a great receiver not simply because he had more other-worldly talent than other receivers. It also was because he outworked everyone with a rare maniacal passion and became one of Bill Walsh's most scholarly students of the West Coast offense.Football in St. Louis could be a lot of fun again if Quick is a quick study.
