This is tough to say...but if TO were to come and Crayton showed me he was coming back from injury right on track to continue where he was when it happen, I'd keep Keyshawn then use Terry and Peerless as trade bait. TO is Keyshawn, with the added ability of giving us deep threat that Terry and Peerless would be used primarily for. Added with Witten, I would really like the size advantage TO, Key, & Crayton would bring to the table.
Ideal scenerio, we keep Glenn too. Giving equal time between him and Crayton in that #3 spot. Althou how fair is that to either one? Peerless is definatly the odd man out however.
I just also see a much stronger "bond" between Bill and Key. I also remember seeing a shot of TO & Key talking, after I believe the first game between us and the Eagles this year, and they were just standing around "chumming" it up. So maybe they're friends and we don't know about it?
