I'd love to see Lacy leave for the NFL, largely because that would mean that he did fairly well.
But, while he looked more like himself last game, he still has a long way to go to really. 4.6 average against Arkansas is not bad, but ULM and Jacksonville's State's lead rusher averaged 4.3 and 4.6 respectively. Eddie's 4 TDs is not bad, but his average is way, way down from his previous two seasons. There are reasons for that, but 4.2 average (and only one reception), is lagging well behind Ingram's 2010 average of 5.5 (and 21 receptions) and Trent's 5.9 (with 29 receptions).
Basically, to be in the same ballpark at all, he has to get dramatically better, as the defenses get dramatically better. We know he has the talent, but really, we only saw a few glimpses last game of Lacy playing like he'd need to, to really get the NFL's attention. As it is, if things continue like they could, his stock will drop as he puts up mediocre numbers. He's not a top 100 rusher right now. While he would get drafted, to me a lot remains before making the choice to leave for what could be a later round pick. I hope he is close enough to 100%, to really start to return to the level he was at, but leaving for the NFL is not the no brainer it could be at this point.
