In my dis-honest opinion...the Bears may have overpaid for Massie or maybe they didn't.
First of all, continuity on the offensive line is critical - bring back Massie helps to ensure that continuity.
Two, the RT is becoming like a 2nd safety on defense. There's almost no difference between the importance of the pass blocking ability between a LT and RT as you'll find defenses coming off either edge. See Khalil Mack.
Three, Massie gave up 2 sacks in 2018. Only had 4 penalties.
Four, Massie is durable. Missed 2 games over 3 Bears seasons.
Five, we don't have an upcoming RT waiting in the wings. And we don't have the draft ammunition either.
Six, Massie stated he could have went to free agency but took less money to stay with the Bears. Maybe. But the fact that the Bears targeted him over Callahan and Amos says something.
Seven, Massie will turn 30 just before the start of the season. He probably has at least 2 maybe 3 years of quality play in him before he needs to be upgraded.
Eight, Pace knows what he's doing.
