How does Mo get into the NFL if he isn't fully healed in time for combines/tryouts?
Seems like an awfully big gamble to try and make a team as an UDFA and work your way up if you have the opportunity to prove your health in college. Even Rodney came back for a 6th year and that likely earned him some NFL money because he was able to show he was healthy that last year.
If Mo had been looking like a 1st rounder, there are examples of teams taking gambles on kids who had bad injuries their senior years. But for a kid who was probably a Round 4-6 pick when healthy and coming off an achilles...seems like he has a better chance to earn a guaranteed roster spot with a good year in college.
