I don't look at it as the next 'Clinton Portis', but the next rookie RB to have a breakout year. Because Smith is going fairly late in drafts and Portis was a later round pick last year, the comparisons are being made.
The comparison isn't unproven rookie Smith to 2nd year stud Portis, but a comparisonm to their fantasy potential based on their draft status. Starting at RB for either the Vikings or the Broncos is a desirable fantasy position. Denver has a history of RB success, and Minnesota has a dominating O-Line.
Who else would you call this years Portis? The only other likely candidates would be LJ, McGahee, and Toefield. None of them is starting.
Smith should be about a 7th rounder. If he can pick up the blocking assignments, he could make a big impact. Moe will probably steal most of the TD's, but he could me a solid #3 RB option, with a big upside.
Bennett is not going to be back week 8. He is more likely to miss the entire season than be back anywhere around week 8. It's no guarantee the new, unproven surgery is even going to work, and additional surgery is not ruled out at this point.
The meek ain't gonna inherit $#!%....'cuz I'll TAKE IT!
