Zak Keefer of The Athletic reports that the Colts say RB Marlon Mack is back to 100% health for the start of camp. That's noteworthy, given Mack missed last year with a torn Achilles' tendon. Of course, being 100% healthy does not necessarily equal being back to your original performance level. But this is a big step for the veteran back. Mack still can't hope to be more than the #3 RB on this year's Indy roster, but his return could leave Jordan Wilkins without a spot. A near full-strength Mack could also stress the workload for Jonathan Taylor.
