It's not meaningless, it just means it a player with less than three accrued seasons and no contract. If the team offers him a 1 year vet minimum contract it means that he cannot neg. with other teams. It also means he has no contract unless the original team offers him one.
Not really, his immaturity had a lot to do with him being a 7th round pick, but it's not like he was a 1st round talent, he was a 3rd to 5th round talent with maturity problems.
Actually I can know that Kelly being on the roster has no bearing on their draft board. Just like I can say definitively that having EJ Speed or Franklin on the roster is not going to affect the Colts draft board.
No, he's an ordinary Day 3 pick that was drafted and released by his previous team because of maturity issues. Just like, if the Colts draft a QB on day 3, they will be an ordinary day 3 pick, only without the maturity issues.
I would definitely say yes!! Reason being there are some potential QB in the 2020 draft that the team can develop under Rivers who will play for the team for at least two years. This will give enough time for the QB to develop his skill sets.
