I play in PPR leagues also, I just cant see even if Bush catches 50-75 passes like LT that I could take him that high. Bush may very well be the next LT, my only thing is he could just as easily be the next Ki-Jana Carter, he still has never played a down in the NFL, and as good as he was in college, thats not the NFL. Good luck.
Ki-Jana doesn't seem like a good comparison because he shredded his knee before he got a real chance to show us what he can do. Obviously there's heightened risk with a rookie, but Bush was essentially the same player last season as he will be this next season. I've watched a lot of RBs play over the past few years and he quite simply blows the doors off of all of them in terms of his combination of instincts, measurables, athletic ability, and football skills.
I'm really not as big of a risk taker as I used to be, but this was a unique situation of the perfect prospect having the perfect skill set for this scoring system. We'll see how it works out, but I'm happy to have #5 as a cornerstone.
