Implications of Fowler trade on 2019 rams

The Rams gave up a 3 and Brown to get this done. Sullivan and Whitworth will be on their last year of their contacts and will need replacements by 2020. If the assumption is the current rookies take their place, then we need new depth. I feel the loss of Brown increases the likelihood that they resign Saffold if he is willing to take a big hometown discount 8 to 8.5 a year. Otherwise, a guard has to be a round 3 pick or a FA.
