We all know Manningham wasn't the brightest, and this limited his time on the field and productivity.
Read this about Ochocinco.
(copy and paste? Sorry, link linking not working for me)
Ocho was lost in the Patriots offense, which limited his productivity.
Anyone here know the intricacies of SF's offense, and does Alex Smith run as many options as the Pats?? ... or are they more like Ocho's Bengels?
I think the answer as to SF's inticacies will determine Mario's failure or success. It will be interesting to see.
