The Cardinals have made it a practice to sign veterans as they are about to start (or just after they get underway with) training camp. This season is no different. The news came out Wednesday evening that veteran safety Tre Boston, who had visited the team earlier in the offseason and so had been a possibility as an addition for a while, would be joining the team. Nothing official yet, but Boston himself tweeted out confirmation.
Boston, only 26, set a career-high with five interceptions last season as a member of the Los Angeles Chargers. Before that, he was one of Steve Wilks' defensive backs in Carolina, playing against the Cardinals in the postseason both after the 2014 and 2015 seasons. He slides into a safeties rotation with Budda Baker and Antoine Bethea, and reunites with former Carolina defensive back teammates Bene Benwikere and Lou Young. Earlier in the offseason, Boston said in an interview he had been disappointed in the Cardinals' original contract offer, so it will be interesting to see if anything changed.
Boston is also the second veteran to arrive. Earlier in the day it was reported that the Cardinals are signing veteran linebacker Arthur Moats. With report day Friday, I'd expect those moves to be announced soon. The Cardinals currently have one open roster spot to get to 90, so multiple additions would mean at least one player being let go.
