I re-watched the play on the ALL 22 yesterday and it looked like he only got a part of the shin down. It wasn't conclusive though from the angles I saw.
However, the announcer was correct that Goff held onto the ball too long. It looked like Goff should have thrown it a half second sooner for a much easier completion attempt. Then once he threw it, he threw it a tad high. I liked how Reynolds went up for it and caught the ball which confirms imho some of your arguments that the CB held Reynolds on the last play of the Eagle game because Reynolds hardly even jumped for the ball compared to the one yesterday. I think he must have been held down.
On the other hand, Jrry is correct that Reynolds should still have been able to bring both feet down because his left leg curled up to his chest after he made the catch. He should have kept both legs straight. It was weird seeing his leg curl up like that when I have seen receivers like Woods and Kupp jump high for passes and kept their legs straight.
