The San Francisco 49ers can buy just about anything with that. But they shouldn’t. They should do just what they have been: signing veterans like Earl Mitchell, getting Jeremy Kerley locked in, adding some depth, and then stash everything until they really know what they have. The coaching staff and front office have been reviewing film, and have some ideas of what skills translate for what players. But how much will they really know before Kyle Shanahan and Robert Saleh have a year with these guys in their offensive and defensive systems? After all, a roster can deceptive; just ask anyone who watched Mike Singletary’s team.
