One game does not a fantasy savior make.
In New York's 41-34 win over the Tampa Bay Buccaneers on Sunday, Brown led all running backs with 71 yards and a touchdown on 13 carries. Behind him, Ahmad Bradshaw got just five carries for 16 yards (he left the game early with a neck injury).
But this was not a stellar performance on the ground for the Giants. They got 510 yards in the air, though, which is what redeemed this team in Week 2.
Brown certainly helped, and he came up huge for New York in two very, very big spots, scoring the game-tying two-point conversion and game-winning TD. Without stellar performances from Eli Manning, Hakeem Nicks and Victor Cruz, however, the Giants wouldn't have been in a position to tie—and eventually win—the game in the first place.
It's never a good idea to rest the hopes of your fantasy backfield on a third-stringer who's had one good game in his career and still, by the way, has yet to rush for 100-plus yards.
Brown could end up being a star, and in that sense, he's a low-risk pickup, but he could also end up being a waste of a roster spot.
One thing that is rather encouraging about Brown is that he had a pretty successful performance against a rush defense that's proving to be pretty good. Say what you will about Tampa Bay, but it is tough on the run. In Week 1, this defense allowed 10 rushing yards to the Panthers. This week, it allowed 94.
But we still don't know how Brown is going to fare for the Giants. We don't know how Tom Coughlin is planning on utilizing him going forward.
We don't know how many carries he's going to get compared with Ahmad Bradshaw and David Wilson. We don't know how much his workload is going to increase in light of this performance.
After two weeks, the jury is still out on whether or not he can be effective from a fantasy perspective, and more than likely, it will be the same case for Brown for the next few weeks.
This isn't to say there aren't a lot of positives where Brown is concerned. He came up big when the Giants needed him. He has good size for a running back (6'0'', 227 pounds) and could potentially be very effective if the Giants continue to utilize him properly.
But it's just too soon to tell.
