The Colts need help rushing the passer and Houston fits the bill. He's missed 21 games over the past four seasons, but has made up for it with 9.0-plus sacks in 2017 and 2018. Houston turned 30 in January.

Houston recorded 32 tackles (25 solo) with 9.0 sacks, 1 pass deflection, 1 interception, and 5 forced fumbles in 12 games last season.

The former Raider will backup Deshaun Watson, following the departure of Brandon Weeden. McCarron has been in the league since 2014 but has only made three regular season starts.

McCarron has attempted 136 NFL passes, completing 64.0% of them while averaging 5.7 net yards per dropback. He has thrown 6 touchdowns and 2 interceptions.

The former Packer will be tasked with providing pass-rushing help for the Rams, though the 32-year-old is not the same player he was in his prime.

Matthews started all 16 games but had a career-low 3.5 sacks last season. It was the fourth straight season his sack total declined.

The former Bengal reunites with defensive coordinator Paul Guenther, who coached him in Cincinnati.

He made 33 tackles and forced three fumbles in 7 games last season.

Cobb will likely replace Cole Beasley in the slot after an injury-ravaged 2018 campaign in Green Bay. Entering his age-29 season, Cobb hasn't averaged more than 46.9 yards per game in any of the past three years. He will likely be a third or fourth option in the Cowboys' conservative passing attack.

Cobb caught 38 passes for 383 yards and 2 touchdowns on 61 targets last season.
