Which do you consider solid? James won the rushing title his first two seasons and then failed to rush for 1000 yards the year following the tear. McAllister was awful upon his return. Gore didn't return the first time. McGahee took 18 months before he came back. The NFL season will be over 18 months after Charles' injury. Ronnie Brown admittedly wasn't very good pre-injury, but his production did dip from the previous season post-injury. Kevin Smith is more akin to Adrian Peterson (and Mendenhall), I'll give you that. But, he averaged 22 yards per game once he came back.McAllister's tear came in Week 3. Charles' tear came in Week 2 (September 18th). Edgerrin James tore his in Week 6 on October 25, so it was only about 5 weeks later than Charles. McAllister returned to a crowded backfield. Charles is returning to a crowded backfield. I expect Charles to be somewhere between James and McAllister (real enlightening). He's got a situation more akin to McAllister's, but his age is closer to James'.Frank Gore missed an entire year following his first ACL tear. He came back the next year only after his second ACL tear (of the other knee). So, it was more than two seasons removed from his first ACL tear before he played again.And, as I said above, I think it's worth noting that out of the above, none of them were speedy "scat" backs like Charles is who relies on elite acceleration/deceleration and cuts. From another site, "[t]he ACL holds the femur and tibia in place and is one of the most critical ligaments to athletes because of its primary function of stabilizing the knee joint during deceleration. Without the ACL, players would fall to the ground due to the knee buckling when applying pressure from either stopping or changing direction. It is only natural for a running back to be hesitant when running during the first year after an ACL injury. Given the speed of the NFL, there is no room for there to be any kind of hesitation and still expect a running back to put up big numbers."Maybe Charles will buck the trend as I said. I hope he does. I don't root for injury and I hope all players make it back 100% from injury. But, you need to draft Charles in the first two rounds to get him. He's either your RB1 or RB2. You are advocating him as not only an RB1, but the #5 RB off the board. Charles' injury is such that I don't think it likely that he's 100% and I don't think it's likely he'll receive either the workload or have the production required to get to top 5 numbers. I'd gladly take him as an RB4.It might be informative to delve into these numbers a bit more:Kevin Smith: tear - mid December 2009, wasn't ready for the beginning of 2010, came back in October, played 6 games and got hurt againRonnie Brown: tear - mid October 2006, came back and ran for 214/916, 33/254 receiving. Very similar numbers to his two previous healthy seasons (207/907, 32/232 and 241/1008, 33/276)Deuce McAllister: tear - late september 2007, wasn't ready for the first game of the season. The saints were really spreading the ball around at that point ... they had 3 backs over 100 carries (Reggie Bush and Pierre Thomas)Frank Gore: tear - 4th game (college) of 2003, ran for over 1000 yards in 2004 (still college)Edge: tear - late October 2001, ran poorly in 2002 but still had over 1300 total yards and 330 touchesWillis McGahee: tear - early January 2003 (all three ligaments), missed 2003, had a monster 2004So, I'm assuming this list is not comprehensive, but it looks like most of these guys had solid following years. The two guys who didn't were not ready to start the season and were (probably) rushed back mid season. Given this, their lack of production could easily have been due to lack of conditioning or something like that. Charles was hurt at the very beginning of last season and looks like he's ready to play.Jamal Lewis: Torn ACL in 2001. Bounced back in 2002 to rush for 1327 yards with a 4.3 avg. Then in 2003 rushed for 2066 yards with a 5.3 avg.Edgerrin James: Torn ACL in 2001. Following year in 2002, rushed for 989 in 14 games. In 2003, rushed for 1289 yards, then had back to back 1500+ yard seasons in '04 and '05.Willis McGahee: Torn ACL in the bowl game before being drafted. Missed entire rookie season in 2003 and bounced back next season with 1128 yards rushing with a 4.0 ypc.Frank Gore: Tore his left ACL in 2001 while in college. Rehabbed all of 2002, returned in 2003 only to tear his right ACL. Returned following year after switching jersey numbers and rushed for 1000+ yards in his last college year. In his rookie year in 2005, as a part timer, rushed for 608 yards with a 4.8 ypc. Following year in 2006, rushed for 1695 yards with a 5.4 ypc.Note: You might want to have precautionary surgery to strengthen a healthy ACL if you are a RB at "the U."Deuce McAllister: Torn ACL in 2007. Came back in 2008 to rush for 418 yards with a 3.9 avg.Ronnie Brown: Torn ACL in 2006. Came back in 2007 to rush for 946 yards.Kevin Smith: Torn ACL in 2009. Came back in 2010 to rush for 133 yards.So, only Ronnie Brown and Jamal Lewis came back to do reasonably well the following season, but only Lewis ran for more than 1000 yards. But, Lewis also tore his in preseason of 2001 and had a long rehab prior to coming back in 2002. He also didn't have to compete for carries with another starting RB the following season.The general rule that I've read is that it takes two years for most players to get back to normal following ACL tears. For that reason, I'm essentially crossing Charles and Peterson (and Mendenhall, Hightower and Moreno) off my list (unless I can get them as my RB4, which I don't think I can).
