the play in question...I don't think Brown is ready. If I recall correctly, the bomb that Mahomes threw late in the Super Bowl (I think it was to Worthy), it was McCollum and Brown that were covering him, and neither of them did a good job on that. Both played a good bit on special teams in the Super Bowl, but I think each of them only played 2 snaps in the secondary -- I suspect that play brought an end to their playing.
I give Brown a pass on this play but not McCollum. It is also the first clean pocket Mahomes had that day, imo
if you watch this play, might want to bench #27 as well (tic) letting him run an out on the G/L!
