The Facts: McDonald, coming off a 30-catch, three-TD season, is having the best offseason of his career.
Diehards Line: This according to CSNBayArea.com's Matt Maiocco. Worth noting: There are observers who feel we've seen the best of McDonald already. Still, he's of some fantasy interest based on his late-season run last year. Garrett Celek, a better blocker, could be the starter, but McDonald is worth watching although Bruce Miller might be the best route-runner at the position as he makes the transition from fullback.
