Yeah I can see that, But San Fran is a complete dumpster fire. Since Harbaugh left they have had 3 coaches and went 5-11, 2-14 and are now 0-5 this season. Who's to say how long Shanahan will even be their HC. Cousins has played a ton of football since he played for Kyle. Why would he go to San Fran when the money will be the same and he can walk into a stable situation where he can win now.
I just think the media is overstating Kirk's desire to be reunited with Kyle.
