I like this pickup a lot. If it weren't for his fumbling issues, I'd love it, which is really strange for a guy with above-average to great hands. He always falls forward, but sometimes, I think he does so at the detriment of making guys miss. He doesn't shy away from contact, but he also doesn't look to make guys miss much either, as a result, you see him tackled at the hips from defenders coming in from the sides quite a bit. And his vision isn't going to make anyone forget Danny Woodhead, but he does a lot of things well. He runs good routes, the aforementioned hands and falling forward, and his size and athleticism creates matchup problems that someone smaller/quicker might not be able to. I think you can't really judge his pass protection skills all that much because I'm not sure he was ever asked to do it in New Orleans, at least not enough to render any sort of real judgment.
He's also got quite a bit of experience returning kicks from his time at Appalachian State. Based on my unofficial stats (I may have missed a box score here or there at the time), I count 58 kick returns for 1365 yards and 24 punt returns for 162 yards. Again, surprising to see a guy with that many returns over a two year period struggle to hang onto the ball, but hopefully, those were more fluky/small sample size than something that will continue going forward. What we do know is that a couple of fumbles here could result in him not seeing the field at all, and thus, make this signing irrelevant in the end.
Time will tell, but I don't see how this kind of signing hurts us at all. Nothing but upside, IMO.
