Jacoby has all the talent...but unfortunately, we've been down this road before. Every time he's had a chance to show what he could do as a starter, he failed to show anything at all.
Now, most of those instances was him replacing Walter...not AJ. So could it be different this time? More experience now, chance for a leading receiver role rather than a opposite receiver role? Maybe. As a fellow AJ owner myself, I'm going to attempt to grab Jacoby, but I'm not going to lose any sleep over it. I also have underachievers-so-far Manningham and Antonio Brown, so I have more hope in them than I do in Jones. Plus, there are always tons of marginal WRs on the waiver wire with upside.
So, yeah, I think he's probably a good gamble. But I'd be just as happy going another route as well...maybe one of the Buffalo receivers that aren't rostered, James Jones is out there in a lot of leagues...there are other options.
