Below are the players and positions that I have interest in.
Resigning Tru would be a high priority but if that didn't work out, I would target another CB instead. Don't think they should head into the draft with no solid CBs on the roster.
I'd let TJM walk and slide Alexander into his spot.
CB - Tru
WR - Garcon
OG - Ronald Leary / TJ Lang / Larry Warford
LOLB - Nick Perry
FS - Duran Harmon
I don't think Harmon or Larry Warford will break the bank. Spotrac has Nick Perry at $8.5M which is something I would do. Fanspeak Ultimate GM seems to value him at around $5M but I seriously doubt that's accurate.
Garcon is the hard one. He's kind of old at 31 but still effective. His age should keep his price reasonable and hopefully his connection with McVay gives us a chance.
For Tru, I wouldn't structure any contract where the majority of the money is upfront making him expendable in a year or two. I'd make year 1 low and put it all in year 5 which he will never see. He's a known commodity so the risk of structuring it this way is lessened.
