You could give Lamb any number and fans will buy it because they are excited about him and want to show their support of him.
It's not about Jerry The Marketer wanting to market the player for more jersey sales. Tons of people who normally would buy a jersey of a 1st round WR pick like this will hold off because they have a fairly recent 88 jersey in their closet and they cant justify the expense of buying a new one just for a different name on the back just yet.
Honestly, Jerry isn't as obsessed with jersey sales as people want to pretend. If he was, he'd change/redesign our uniform and jerseys way more often. Give him credit for this, he's resisted the easy money he'd make just by drastically changing our jerseys.
So if it's not about Jerry marketing the kid for jersey sales, what's he marketing? It's about Jerry marketing the job he's doing as a GM. Handing out 88 to a new receiver and having that guy blow up is all about him wanting people to give him credit for finding the next great 88 and building the core of a new dynasty. (Sometimes I think he forgets how much of the '90s dynasty's success was owed to our defensive ferocity. He just remembers the hype of the triplets, so he thinks stocking the cupboard at QB-RB-WR means he's built a new Super Bowl team and he's done his job.)
